aac(4) can't produce/save crashdumps

Hi,

This issue is related to
http://leaf.dragonflybsd.org/mailarchive/bugs/2005-12/msg00047.html on
problem no. 2 but this is using an aac(4) RAID controller. This issue
is tested on an IBM x3650 machine with manually-generated panic
through ctrl-alt-escape method and an actual fatal trap error
(debugging an ixgb device driver).


# /etc/rc.conf
. ..
dumpdev=/dev/aacd0s1b    # swap device
dumpdir=/home/crash
. ..

# /etc/sysctl.conf
kern.sync_on_panic=0

With ctrl-alt-escape, calling a dumpsys will just hang my system.

db> call dumpsys

dumping to dev #aacd/0x20001, blockno 10486216
dump 3071

Thanks,
Archimedes
