Public bug reported:
I am using 9.04. uname -a says:
Linux arturo 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:57:59 UTC 2009
i686 GNU/Linux
I can lockup my machine by executing a long (> 15 mn) compilation (it
saturates the processor). Before 10-15 mn max, the machine locks up
completely. The caps lock LED starts blinking, and the computer does not
respond (even to Alt-SysRq).
I could trigger this reliably 5 times in a row.
This seems to leave nothing in the logs. However, I have a photo of the
"kernel BUG" output on the console, that I will attach.
I have just updated my BIOS, hoping that it could make things better,
but it does not.
