Kernel Panics due to SMBFS (1.7) on 10.7 Lion

Question

Hi Everyone,I recently did a clean install of OS X 10.7 Lion, and am now having a regularly occuring problem with kernel panics due to smbfs (1.7). After mounting a Windows shared drive using samba, and then accessing files from this drive, a kernel panic occurs. It also seems to occur when attempting to dismount a samba drive. I did not have this issue with Snow Leopard at all, so I&#x27;m assuming it is an issue with Lion. I have copied the kernel panic below. Any ideas? Thanks everyone!KERNEL PANIC LOG BELOWThu Aug 11 07:36:36 2011panic(cpu 0 caller 0xffffff80002c268d): Kernel trap at 0xffffff80002b3257, type 14&#x3D;page fault, registers:CR0: 0x000000008001003b,

Boot in safe mode by holding down the shift key at startup, and test. Same problem? If not, it&#x27;s caused either by Parallels or by the DisplayLink driver.

sainzeo · Answer

Thanks for the suggestion! I booted into safe mode and tested and had the same issue happen. I have attached the kernel panic log in case it is different from the previous one. Any other ideas?Interval Since Last Panic Report:  378813 secPanics Since Last Report:          3Anonymous UUID:                    FA55FD9A-5A22-4CA9-8A8E-05D5CB9046FBThu Aug 11 08:44:00 2011panic(cpu 1 caller 0xffffff80002c268d): Kernel trap at 0xffffff80003197b2, type 14&#x3D;page fault, registers:CR0: 0x000000008001003b, CR2: 0xffffff0011d260d8, CR3: 0x0000000000100000, CR4: 0x00000000000206e0RAX: 0xffffff0011d26000, RBX: 0x0000000000004107, RCX: 0x0000000003000000, RDX: 0xffffff800c9de248RSP: 0xffffff80e5bb3e70, RBP: 0xffffff80e5bb3e80, RSI: 0x0000000000004107, RDI: 0xffffff80d7c42c90R8:  0xffffff80003ce870, R9:  0xffffff80e5bb3d34, R10: 0xffffff80e5bb3cf8, R11: 0xffffff80002d8200R12: 0x00000000000000a2, R13: 0x0000000000000000, R14: 0xffffff800e9ca108, R15: 0xffffff8008030001RFL: 0x0000000000010286, RIP: 0xffffff80003197b2, CS:  0x0000000000000008, SS:  0x0000000000000010CR2: 0xffffff0011d260d8, Error code: 0x0000000000000000, Faulting CPU: 0x1Backtrace (CPU 1), Frame : Return Address0xffffff80e5bb3b30 : 0xffffff8000220702 0xffffff80e5bb3bb0 : 0xffffff80002c268d 0xffffff80e5bb3d50 : 0xffffff80002d7a3d 0xffffff80e5bb3d70 : 0xffffff80003197b2 0xffffff80e5bb3e80 : 0xffffff7f815ff07f 0xffffff80e5bb3e90 : 0xffffff7f815f9ecc 0xffffff80e5bb3f00 : 0xffffff7f815f8bfa 0xffffff80e5bb3fb0 : 0xffffff8000820057       Kernel Extensions in backtrace:         com.apple.filesystems.smbfs(1.7)[4DB5DCA8-58D3-3DD2-8E91-1508ED8210E3]@0xffffff 7f815dd000-&gt;0xffffff7f81617fff            dependency: com.apple.kext.triggers(1.0)[AE7BE743-CEA4-3E66-818F-C34233D9CF64]@0xffffff7f81 5c6000BSD process name corresponding to current thread: kernel_taskBoot args: -xMac OS version:11A511Kernel version:Darwin Kernel Version 11.0.0: Sat Jun 18 12:56:35 PDT 2011;

Linc Davis · Answer

Then it&#x27;s not the third-party software. This is either a bug in Lion (likely) or a damaged installation (unlikely.) To rule out the latter, boot from your recovery partition (command-R at startup) and reinstall Lion. Obviously you will have backed up all your data first.

Starting the re-install now. Will update this as soon as I get some testing done on the new install. Thanks for all the help!

sainzeo · Answer

Well, did a clean install from the recovery partition and am still seeing the same problems. I&#x27;ve noticed that after mounting the SMB drives, if you open a Finder window and browse through the connected drive by going to the drive name under "SHARED" in the left-column, Lion will mount a duplicate of the drive if you select the same volume. For instance, I mounted a volume by going to "Connect to Server" and typing in: smb://&lt;server&gt;, then selecting the "DATA" volume. If I then open a Finder window and select &lt;server&gt; underneath the "SHARED" list from the left-hand column, then select the "DATA" volume again, instead of using the already mounted volume, it mounts another one.Then, if I go to unmount the drives, I get the kernel panic. The kernel panic also occurs though even if there aren&#x27;t duplicate volumes mounted as well, but it isn&#x27;t as consistent.I should also mention that I had been using TrueCrypt with MacFUSE. I noticed that after installing MacFUSE, exploring through mounted volumes through Coda (a web development app) caused Coda to crash and then Finder. My thought was maybe it was MacFUSE causing the problem, so I uninstalled it. After uninstalling it, Coda started working fine again, but the kernel panics still happened from time to time.Then, I realized that Parallels installs MacFUSE in order to mount Guest virtual drives on the Mac. So I removed Parallels and am now testing once again. Any other thoughts while I test?Thanks again!

Linc Davis · Answer

Lion has a completely new SMB/CIFS compatibility subsystem, no longer based on Samba, so it wouldn&#x27;t be surprising if there were bugs. That&#x27;s what I think is happening.

sainzeo · Answer

Yeah, just submitted a bug report to Apple. Same exact behavior is happening on another machine that I installed Lion on. Hopefully this gets ironed out real quick or I&#x27;m going to have to reinstall Snow Leopard 😟.

matthewadams · Answer

I gotta join you on this one.Multiple kernel panics due to SMBFS even at the same adresses. Pretty much looks like a bug indeed.Interval Since Last Panic Report:  83056 secPanics Since Last Report:          6Anonymous UUID:                    EE2DEBA4-3690-4EF0-8DA0-3D6A576A963BThu Sep  8

sainzeo · Answer

Well I&#x27;m glad I&#x27;m not the only one having this issue. I did submit a bug report to Apple on August 12th, but have yet to hear anything back about it. I feel this is a pretty major issue - luckily there are workarounds. I&#x27;m surprised I haven&#x27;t heard more about this from other users...

matthewadams · Answer

Can you give me some details on the workarounds?The computer in question doesnt have MacFuse (or Parallels for that matter) installed, but Paragon NTFS but I doubt those interfere with smbfs because they are working on disk-level while smbfs is not.

sainzeo · Answer

Well, it is probably not the best workaround, but it is working for the time being.If you have another Mac around, make sure it is still running Snow Leopard, Leopard, etc. - anything but Lion. On this machine, connect to the SMB drives you were trying to connect to on your Lion machine.Next, on the NON-Lion machine, enable "Remote Login" under the Sharing - System Preferences pane.Then, on the Lion machine, download and install Panic&#x27;s Transmit (http://www.panic.com/transmit/). Even though it isn&#x27;t free software, I haven&#x27;t had to pay for it - I wonder if there is limited functionality - if there is, I haven&#x27;t noticed it yet. Once Transmit is installed, setup a new "Favorite", using the SFTP protocol and make sure the server address points to the NON-Lion machine. Use the NON-Lion machine&#x27;s account information for the User Name and Password fields. Finally, in the "Remote Path" field, enter "/Volumes/". This will allow you to see any mounted volumes on the NON-Lion machine, which will include the SMB drives you were trying to connect to. After saving this Favorite, connect to it, and I believe you should see a mounted volume on your Desktop that will allow you to see the SMB drives. I can&#x27;t remember if I had to setup Transmit to mount the connection as a disk or if it did it automatically though, so if you&#x27;re having problems, let me know and I can try and figure it out.Hope this helps!

matthewadams · Answer

Ah i see... wouldnt it be easier to just mount the SMB Share from the SL Machine to the Lion Machine over AFP ? Cause I&#x27;ve been using AFP and havent seen any problems with that.Anyway, the machine I was talking about is running a corporate network enviroment and thus isnt really eligible to such a rather complicated/circular workaround 🙂I&#x27;ll get direct hands on with the machine this weekend and do some more investigations and also file a bug-report to apple then.Do you have any specific ticket number I could include when filing?Thanks!

sainzeo · Answer

Yeah, that would be a lot easier, but unfortunately, when I connect to the Snow Leopard machine using AFP, I&#x27;m unable to see the /Volumes directory and therefore can&#x27;t see the SMB drives. Maybe I&#x27;m just not doing it correctly? Definitely possible. 🙂The Bug ID # from my report is 9944016.Hopefully they start moving on it once they see another report filed about the same issue!
