Dual Quad Core - freeze after sleep
besides the restart-after-sleep Problem my MacPro sometimes freeze after awake from sleep. It happend twice since I own the Pro. Because of the restart-after-sleep issue I happen to send it to sleep quite often, so maybee it was triggered by sleeping to often, who knows.
The machine comes up as usual, then upon the first app you try to access the UI just stalls (showing the spinning beachball). The only possible solution is to hard-reset and reboot.
One time I was "lucky" and I had a Terminal and Activity Monitor running. I think otherwise you would just see the spinning beachball before rebooting.
I have a Screenshot made with my digicam: http://cachescrubber.org/IMG_1225.jpg
It was still possible to focus the Terminal window and the shell was still accepting commands. Every command faild to execute with "Cannot allocate memory". You see 90% of 6GB RAM free in the Activity Monitor window ....
There is no ChrashReporter coming which is usually the case after a crash. The only error message I found in the logs is
disk0s2: memory allocation error.
I have a call open with apple care regarding the restart-after-sleep, so I allready did a lot of tests (AHT, passed, memtest|OSX, passed) and of course SMC/NVRAM resets.
The OSX instance running had Parallels and Vmware installed (both installing a bunch of kernel extensions). Otherwise it's 10.5.2 + all updates (incl. ATI firmware update).
Maybee other experiencing a freeze after sleep should check their syslog for "memory allocation error".
I'm unsure wether this is another OS/Firmware issue or in deed a hardware problem. I must decide this week wether I try to get replacement hardware (via DOA) or just wait for a possible software update. What do you think?
