[Bug 572162] Re: Sudden reboot happens randomly

[Kevin Mauser]

As Moraus said, after disabling KMS the problem goes away.  You can
disable KMS by adding "nomodest" in your grub (/etc/default/grub) file
like this:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"

It'll make the boot splash screen not look at nice, but at least your
computer won't randomly crash.  From my understanding, it seems that the
reason this doesn't happen with Karmic is because KMS (Kernel Mode
Setting) was added into Lucid and wasn't in Karmic.  You might want to
check out this link for more information:
https://wiki.ubuntu.com/X/KernelModeSetting

This isn't really a solution - it's a temporary workaround.  It'd be
nice if someone would like into this.  I haven't been able to find
anything useful in the log files though.
