I think it is something to do with the power management. Sometimes when I wake the MBP from sleep, it won't boot and I have to do a hard reset. Here is the latest log. I have also sent previous logs to parallels. Parallels VMM driver is loaded on startup. Is there a way to disable that ? Someone please help. panic.log: Description: Panic (system crashes) log Size: 12.49 KB Last Modified: 5/23/06 9:26 PM Location: /Library/Logs/panic.log Recent Contents: ...
