I recently enabled SW_WATCHDOG in my kernel, but when watchdog triggers a=20
panic, no crashdump is taken although dumps are enabled. What could be=20
causing this?
rc.conf has=20
dumpdev=3D"/dev/ad1s3b"
dumpdir=3D"/usr/tmp/crash
and ad1s3b is a swap partition with enough space to take a crash dump. I'm=
=20
testing by going into single user (so I can do umount -a to save on some=20
fsck'ing) and waiting for watchdog to kick in. When it does, there's the =20
panic ("watchdog timeout), a list of interrupt counts is printed and the=20
uptime displayed - and then, the box just sits there (the CPU fan starts to=
=20
go on high rpm at this point, too, something seems to go into a tight loop).
My kernel configuration is attached, the system runs 5-STABLE as of yesterd=
ay.
