For what it's worth, this bug is not debian-specific, nor does it have anything to do with XFS. I'm seeing a similar regression on Fedora [15|16] systems. The bug was not present in the 3.0.x (or older) kernels, but is still present in 3.1.x and 3.2.x. I haven't had a chance to test 3.3.x yet.
My particular setup has a pair of 3Ware 9550SX cards plugged into PCI-X slots on an Asus M2N-LR motherboard. I can provide more details if necessary. I haven't reported this problem upstream to Fedora or the kernel.org due to an inability to save the kernel messages due to the system being unusable, but in my case the kernel log is full of scsi command timeout messages. - Solomon -- Solomon Peachy pizza at shaftnet dot org Melbourne, FL ^^ (mail/jabber/gtalk) ^^ Quidquid latine dictum sit, altum viditur.
