FreeBSD 9-R amd64 - graid, should it survive 'pulling' a disk?

Hi,
I've got a Supermicro X8DTL-IF running amd64 FreeBSD 9.0-R, using the
onboard RAID (ICH10 based) and graid, with a RAID 1 mirror comprising of
two Intel 320 series SSD's.
This works fine - but doesn't survive 'pulling' a disk. I realise this may
not be a 'typical' disk failure scenario (i.e. the device just
"disappearing") - but should it survive?
At the moment I get a panic with:
"
(ada0:ahcich0:0:0:0): lost device
g_vfs_done(): raid/r0p4[WRITE(offset=23737925632, length=131072)]error = 6
/usr3: got error 6 while accessing filesystem
panic: softdep_deallocate_dependancies: unrecovered I/O error
cpuid = 2
...
"
In the middle of the output is:
"
GEOM_RAID: Intel-441dffb: Disk ada0 state changed from ACTIVE to OFFLINE.
"
(Which is what you'd expect to see).
I can get more details - just thought I'd ask to see if this is something
it should just cope with (i.e. having a disk yanked)?
Thanks,
-Karl
