It was pretty quick. I suspect it happened before it really got around
to mounting file systems, but I'm not sure. There was an extensive
backtrace before the kernel panic, but all I get to see is the tail end;
the rest is off the screen, and after shutting down interrupts, trying to
scroll back doesn't work. Is it worth copying the tail end of the
backtrace from the screen?
april:/farhome/hendrik# ls /var/log/boot*
april:/farhome/hendrik# cat /var/log/boot*
(Nothing has been logged yet.)
The problem is intermittent. On a successful boot, does the /var/log/
boot get overwritten? If so, should I try a live CD to get to look at
it? Or does it get appended to or rolled over?
oooh! What happens if the / partition is full? Can that cause a kernel
panic? It happened recently, but as far as I can tell by memory, it
became full only after a successful boot, and I have since deleted a lot
of space. / contains /ver, /tmp, and all of the usual top-level
filesystems except for /usr and /farhome, which are on LVM RAID
partitions. / is a reiserfs. /farhome contains most user files. /home
is small, and is part of /.
