Hi
I've 2.2.5-stable for a while now, cvsup'ing every once in a while. No problems
at all. The machine has continously up for over a year now, barring power
failures etc.
The machine is a 486/100 NCR Globalyst 525 with an IDE disk, Adaptec 152x SCSI
card and a Seagate 2 gig scsi disk.
A short while ago the scsi disk spun down and the machine crashed (rather
panic'd).
Relevant lines from /var/log/messages follow. Could someone please explain
them to me.
