Hi Peter!

Thanks for the detailed bug report.

> 6.8.8+          WORKS   Revert "scsi: core: Consult supported VPD page
> list prior to fetching page" - This reverts commit
> b5fc07a5fb56216a49e6c1d0b172d5464d99a89b (this is the first bad commit
> of my bisect session, see below, and a single patch as part of the

The puzzling thing is that the patch in question restores the original
behavior in which we do not attempt to query any pages not explicitly
reported by the device.

Can you please send me the output of:

# sg_vpd -a /dev/sda
# sg_readcap -l /dev/sda

where sda is one of the aacraid volumes.

Thanks!
