>Description:
Accessing my tape drive randomly causes my FreeBSD 7-STABLE/amd64 system to crash. This has been going on for at least a couple of months, but I finally got a kernel dump to play with. I typically see this when running a backup with Amanda, and as soon as the first filesystem dump starts to flush to tape, the system reboots.
My kernel is very slightly changed from GENERIC, with PMAP_SHPGPERPROC increased for PostgreSQL and the re(4) driver disabled (because it only works when compiled as a module; different issue).
$ cat KANGA
include GENERIC
ident KANGA
option PMAP_SHPGPERPROC=400
nodevice re
The only compiler option in /etc/make.conf is "CPUTYPE?=core2". In short, this is very nearly a generic system.
