6.1 quota bugs cause adaptec 2820sa kernel to crash ?

FreeBSD 6.1-RELEASE, p4 xeon system, adaptec 2820sa SATA raid controller
with all 8 disks in use.
Two arrays are present - a mirror to boot from, and a 6-disk raid6 array
of size 1.8TB.
I am aware that there are problems with quotas in 6.1, but I am
successfully using them with 6.0-RELEASE and an adaptec 1610sa. I figured
it couldn't be any worse...
-----
After loading, the system frequently (multi-daily) crashed with the error:
Warning! Controller is no longer running! code=0xbcef0100
(after a page or so of aac0 timeout messages)
So I disabled quotas on the system, and it has been completely stable ever
since.
-----
Does anyone understand the mechanism wherein the 6.1 quota problems could
cause a raid controller kernel to crash ? Is that possible ? (it seems
to be)
Are there workaround for the 6.1 quota problems, as in "they don't work,
but if you sysctl this and set this, they will" ?
How close are we to working quota code on 6.1, and will I be able to just
patch some files in /usr/src and recompile my kernel, or will it require a
full rebuild of the OS ?
Thank you.
