Re: I need help debugging a random lockup

Not sure about the cpu temp, I don't have any monitoring on it, the air
blowing out the back is a bit warmer than I expected it to be though..
I'll try and get temp monitoring working tonight or tomorrow (I hadn't
really considered it seriously until you mentioned it).  I'll try
swapping nvidia driver as well.

The workstation has one SATA disk, via controller (built into the

I have virtually the same setup at home (ati card instead of nvidia,
opteron 248 instead of 246, different brand of ram), but don't seem to
run into the freeze problem at home (that is, I can't remember it
happening)  .. I'll try the oo calc thing tonight though and see if it
works here.

Thanks for the suggestions : )
