Hi All,

I don't see how they could be related. I've committed a fix for the Areca problem.

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'.

If I've missed something, please feel free to point me to the url!

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.
