Even though the SCSI status is CHECK CONDITION, the data-in

is a READ command when the sense key is RECOVERED ERROR.
Yep, of course.

Some months ago, I had problems with a mis-behaving disk that failed
domain validation on a fusion card resulting in an infinite loop of
domain validation. At the time Eric proposed a patch to the mptspi
driver to reload devices with parameters previously negotiated when a
reset occurred.

From memory, between SPC-2 and SPC-3 the INQUIRY allocation

This patchset adds a generic ring buffer interface and converts bsg to
use it.
The scsi target infrastructure invented its own mmap ring buffer
interface. It seems that kevent would use a slightly different ring
buffer interface. I think it would be nice to have common ring buffer
code rather
This converts bsg to use the generic ring buffer code.
A new data structure, bsg_fd, is introduced to let each process to
have its own ring buffers (that is, several ring buffer pairs could be
attached to one bsg device).

We have a 4GB Emulex HBA with 8.1.6 lpfc driver. The distribution is

we see the following panic.
Has any one seen this before?
