9.0-release panics with ASR_COMPAT and raidutil

My box panics when I use raidutil tool to turn off write-back for
arrays and disks, as advised for database setup (because of no
battery) and when getting status.
Panic occurs immediately after issuing command 'raidutil -d 0 -w off
d0b0t0d0', but sometimes it manages to complete and echo that
write-back has been turned off.
Several minutes after that it panics anyway, maybe on next disk, maybe
on 'raidutil -d 0 -L all' to get information about status, maybe on
Sometimes it panics after only one informational command 'raidutil -d
0 -L all' (immediate and several minutes later).
Kernel config:
include         GENERIC
ident           CTRL1
options         SC_HISTORY_SIZE=2000
options         IPFIREWALL
options         IPFIREWALL_FORWARD
options         DUMMYNET
options         QUOTA
options         RACCT
options         RCTL
device          smbus
device          smb
device          ichsmb
device          ichwd
options         ASR_COMPAT

raidutil is from port sysutils/asr-utils, ASR_COMPAT is added to
kernel config to get it working.

Several panic textdumps:
No consistent backtrace among them - all different, so I am not
including any in this message.

vmcore.* dumps are preserved for a while, so they can be used if needed.

I have to say that previously this box was running 7.4-release, and at
least informational command 'raidutil -d 0 -L all' did not lead to

Any hint to help debugging this issue would be greatly appreciated.
