I recently upgraded from Lion to Mavericks (from App Store), and now my iMac reboots at random. The developer preview had similar issues, but there was a preview update that resolved this issue. The iMac is a 3.06GHz Intel Core 2 Duo with 16GB RAM. I didn't have this issue under Lion.
Update to my issue: I reset the SMC and performed disk repair to no joy. After that, I decided to unplug all external drives, including the drive with my time machine backups. Everything appeared to operate OK. So, I plugged in one external drive at a time and waited. After plugging in my drive for time machine, it decided to reboot sometime later.
This issue seems to come back when the drive hosting my time machine backup is plugged in. It is the backup from Lion. With this issue being hit or miss I don't want to lose my ability to go back to what was working and keep my data.
Last update (hopefully): I traced the logs and problem back to my time machine drive. Even though the drive was happy with Lion, Mavericks and it had a falling out whenever Mavericks would try to write to the drive. I copied the time machine to another drive and re-formatted the original time machine drive (after repairing the disk did not work). Now the Mac is up and running and appears to be stable.
Besides what the other posts say to check the external peripherals, add "check the disk integrity of your Mac's drives" to things to try.
This is bad.... I hope someone solves it asap ....
Same issue here, iMac 21.5 Mid 2010 i3 3.06GHz 12GB Ram. Freezes every 15-20 minutes then reboots, showing kernal panic message.
Startup your Mac in Safe Mode
A Safe Mode boot takes much longer than a normal boot so be patient.
Once you are in Safe Mode, click Restart from the Apple () menu.
Then see if it reboots.
Didnt help me... Late 2011 mac book pro....
My Mid 2010 MBP with Mavericks has rebooted at least twice today while I'm working. I've been having Vista flashbacks. It's quite traumatic and makes it a bit difficult to work.
It didn't do this last night, when I wasn't hooked into my dual monitor set up. Perhaps it's something with the new FullScreen Dual monitor desktops features.
I think that this one solved my problem... Apperently the belkin driver caused a kernel panic.
Try posting a question there... And add your kernel panic dump (it's in /Library/Log/DiagnosticReports) it should be named with the dates so add the latest.
That's the downside of major upgrades... They can screw things up.... 🙂
Good luck!
Same here. Happens on 4 different iMacs and Mac Mini.
Thanks for the tip. I'll keep this site in mind!
I have a 2011 27" Core i5 3.06 iMac and I'm having the same problem. I spent the night on a support chat with apple the night after Mavericks was released. They had me reinstall with a fresh copy of the OS and then restore from my TimeMachine backup. ( A process that I have already done before the chat) Things seamed to be fine for a while, but then it started again. I wish I know what the error log is telling Apple every time I submit them. I wish there was a way to go back to Mountain Lion on that computer. I think the problem is Time Machine relaated as well .
I also have issues with kernel panics since upgrading to 10.9, occuring randomly, at average 5 x a day of use (mid 2010 MB Pro 6,2, 8 GB Ram).
Already the install was near to impossible due to kernel panics. Did not have this before. I did a clean install from a selfmade bootable usb drive, because 10.9 would not install over the previous system with lots of diverse problems (unable to install on hd etc.) this was a very bumpy ride so far.
Bought a new hdd because was suspecting that (now from 320 GB Hitachi to 256 GB Sandisk SSD). I attach my latest panic report. Maybe anyone has a clue? I am not so much into the matter. Hopefully 10.9.1. will resolve this and the update will be released today ;-)
Will think twice about doing a .0 upgrade next time (actually I skipped both lion and ML for stability concerns, and now: voilà).
Any help will be appreciated

We are currently having problems on 10 different Macs. 4 of them had a clean install. Guess what. Even without installing any of software after clean install, iMacs are restarting itself without reason. It also started doing random restarts on my 2011 MacBookPro. What a rolercoaster. Apple, please fix it. We can work like that.
Same Problem here!
MBP 2010 after updating to Mavericks it starts to reboot every now and than. Than i did a clean install still same Problem ! Now i tried to make another clean install, i tough maybe something went wrong last time but now it reboots always during the installation process! I think my only option is to install from the cd which was included with my Mac.
(i think snow leopard)
I got the same problem on a 2012 Macmini after the update. I have now disabled time machine (I use a network based timecapsule) to see if it helps.
