This has already been reported I think, but here it is again. In some
bugzilla somewhere this has been incorrectly reported as a software Raid
vs. Promise driver incompatibility; in fact, it appears to be a problem
when both SATA channels are being used at the same time (which obviously
happens a lot with raid!)
How to trigger it:
# cat /dev/sda > /dev/null &
# hdparm -t /dev/sdb &
# hdparm -t /dev/sda &
Well, I'm not familiar with this problem, at least.
Can you provide info as described in REPORTING-BUGS (in the kernel tree)?
Can you define ATA_DEBUG and ATA_VERBOSE_DEBUG in
include/linux/libata.h, and provide output when it deadlocks?
Did you try 2.6.9-rc1 snapshot?
If nothing else, can you record the bug at http://bugzilla.kernel.org/
to make sure its not lost?
