I am not sure if this will be of any use to anyone. An Oct 22 -current
kernel panic'ed with the following data. I did an Adaptec verify of
the 3 disks involved in the ccd config of that filesystem and they
all turned up clean.
The panic occured during the 'fastrm' phase of the news expire and
machine is a busy news and cache server.
There have been previous panics on this machine, but I didn't have
the kernel set to dump, so haven't been able get any reports (nothing
occured in syslog from those panics).
I have also been getting the following:
Oct 24 18:02:06 disa /kernel: NMI ISA 30, EISA 6
Oct 22 16:46:09 disa /kernel: NMI ISA 30, EISA 6
Oct 21 14:12:08 disa /kernel: NMI ISA 20, EISA 6
Oct 17 02:10:25 disa /kernel: NMI ISA 30, EISA 6
which may be due to a problematic graphics card - due to be replaced
shortly. I have 2 other identical machines (but not as busy) which
haven't panic'ed yet.
