I've reproduced the Areca problem from previous threads this year, and was wondering if it's still broken, or if there's anything I'm missing?
Here's what happens:

Here's the specs:
FreeBSD 6.2-REL, i386 GENERIC kernel (installed today [many times over])
da2: <Areca ARC-1160-VOL#02 R001> Fixed Direct Access SCSI-5 device
(12 chhannel SATA Raid, Maxtor disks, with 'Disable Maxtor' under 'HDD Read-Ahead Cache' set)
Firmware Version - V1.43 2007-4-17
BOOT ROM Version - V1.41 2006-5-24
Additional info:
- Volumes are Raid5 and Pass-Through drives
- Pass-Through drives fail just like the Raid5 volumes do
- Each time it crashes, disk i/o is SCREAMING'.

But if not, it seems whatever bug in this driver existed, did not go away...
(Sidenote: Gotta give a big thanks to the whoever is working on these drivers, once you get working with big disks, it takes A LONG TIME to figure out what's wrong... A fsck takes forever... Not whining, actually I'm really meaning to thank the driver writers for wading through this thick muck!!!)

There are locking problems in the arcmsr driver. I fixed them in HEAD but not in 6-STABLE yet. I really don't have time today to generate patch; I encourage someone to look at the commit I made on July 31 and
backport those changes to 6-STABLE.

Scott

That's excellent to hear!

For the record, are these the most current changes you speak of?:
(I'm reading through the source, perhaps eventually I'll be able to help more...)
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/arcmsr/

- I am not capable of backporting the changes,
+ but I will gladly test any changes this with a GENERIC kernel once they make it to STABLE
