Comment 7 for bug 1215155

It looks like this is a regression introduced by upstream commit 66c28f9 ("[SCSI] sd: Update WRITE SAME heuristics"). This commit has been introduced into the Raring kernel 3.8.0-29.42.

The good news is that the fix has been merged upstream with 7562523 ("[SCSI] Don't attempt to send extended INQUIRY command if skip_vpd_pages is set"). The bad news is that it hasn't yet hit the Raring kernel.

I've uploaded a test kernel containing the fix. Could anyone facing this issue check wether it solves it? Here's the link to the test kernel:
