Hi Martin,
A bug was opened against the Ubuntu kernel[0]. After a kernel bisect,
it was found that reverting the following commit resolved this bug:
commit 66c28f97120e8a621afd5aa7a31c4b85c547d33d
Author: Martin K. Petersen <martin....@oracle.com>
Date: Thu Jun 6 22:15:55 2013 -0400
[SCSI] sd: Update WRITE SAME heuristics
The regression was introduced as of v3.11-rc1, but it also made it's way
into the stable trees.
I see that you are the author of this patch, so I wanted to run this by
you. I was thinking of requesting a revert for v3.12, but I wanted to
get your feedback first.
Thanks,
Joe

James queued this up for 3.13

Maybe we should try to convince James to take it into 3.12?

a try first. If the issue still persists, I'll ask the bug reporter to
upgrade the firmware.

The bug reporter confirms that your patch fixes the bug. Any chance
this patch can make it into 3.12?

FWIW, I don't think reverting the WRITE SAME patch is an option -- it
