Sorry for the late reply. We just had another GPF, this time the logs
showed four of them in a row. I show the relevant parts of the log below.
The processes affected were nfsd, smbd, nmbd and ntpd.
So far we haven't been able to pinpoint anything in particular that might
trigger these GPFs. They just happen from time to time, like once every
week or two.
After this last hang, I installed the latest kernel from unstable. To
be precise we're now using
kernel-image-2.6.11-9-amd64-k8_2.6.11-2_i386.deb. If we see any
similar problems I'll try to report them here.
Thanks!
