Comment 17 for bug 259156

The machine has locked up solid twice in the last week.

ssh connections freeze and timeout, and the console keyboard does not
respond (no VT switching or any other feedback from keyboard input).

The logs show nothing, no errors. I checked the disk with smart, and it
reports no errors.

So I went back to the hardy up to date generic kernel (was running the
rt kernel before)

I removed the acpi=off noapm options from the kernel startup.

X still does not start via GDM, and I was running GDM at the time of
both failures.

I'll turn off GDM for a few days to see if the freeze still happens.

just keeping you posted.
