Hello List,

I am trying to get a crash dump but am unable to with FreeBSD 6.3-RELEASE-p2

dumpdir="/var/crash"    # Directory where crash dumps are to be stored
savecore_flags=""       # Used if dumpdev is enabled above, and present.

Z2873# sysctl -a |grep physmem
hw.physmem: 259481600
Swap: 1024M Total, 1024M Free
Z2873# dumpon -v /dev/ad0s1b
kernel dumps on /dev/ad0s1b

reboot -d
dumping 255M 2 chunks

Then nothing - the system doesn't reboot and I have to hard reset it.
When it comes back up there is no crash file in /var/crash

from /var/log/messages:
Sep 17 07:28:12 Z2873 kernel: ad0: 28615MB <IBM DJSA-230 JS6OAB0A> at 
ata0-master UDMA66
Sep 17 07:28:12 Z2873 kernel: Trying to mount root from ufs:/dev/ad0s1a
Sep 17 07:28:12 Z2873 savecore: no dumps found

Is this broken?
