Crashing when waking from sleep

[bld44]

This is the second time this has happened to me this week, never before. When I return from sleep, instead of getting the login screen, everything is black and the system completely reboots.

When I return, I get the "The computer was restarted after Mac OS X quit unexpectedly" error. I took a picture of both. Can anyone decipher what either of these mean? The second looks like a kernel panic, which I have never had on my system (since 4/07).

Yeah, it's got the read/write errors coming up. Do you have any external USB devices? Maybe use Disk Utility to verify your drive(s), too. 🙂

This could be a symptom of hard drive failure so I'd run some checks on it.

Reset your PMU as well incase something screwy is wrong with it.

No USB devices, but have been having problems with my stock western digital drive that came with my macpro (clunking). I got the error "Volume header needs minor repair" a few weeks ago during a disk check. I need to replace that drive anyway, I just don't trust it anymore.

Did you try repairing it?

 

[bld44]

Absolutely. I did it when I updated to Leopard. I ran verify disk today, nothing out of the ordinary, as well as repair permissions. A few things on permissions, but we'll see if I continue to get crashes.

Well remember to keep everything backed up in the meantime! 🙂

Got another one, looks to be similar to the others. My first ever kernel panic during general use, great.

 

[mad jew]

Have you verified the disk again? It might need replacing.

Getting exactly the same on my PowerMac. There are a few threads on this on the Apple discussion forums, too.
