I'd have thought that the severity of this problem is not matched by
the response.

Is it reproducible? If so, is there any change that it can be retested
under a 2.6.29-based kernel?
Thanks.

OK, I assume that the scsi driver did something bad to sysfs and
that sysfs then fell on its face.
Really, given the frequency and imaginativeness with which drivers
abuse sysfs, the driver-core should be more robust.
Kay, would you have time to plunk through this and see if we can
strengthen the sysfs code a bit so it doesn't crash?
But the core bug is presumably in the mptsas driver. Perhaps you can
also see if you can work out what it did wrong?
Thanks.
