Bug Description

When I try to boot 3.16.0-18.25 on a POWER8 VM, I get the following in a hard loop on the console:

[72319.154290] sd 0:0:0:0: Can't map DMA_BIDIRECTIONAL to read/write
[72319.154413] sd 0:0:0:0: couldn't convert cmd to srp_cmd

Reproducible with subsequent reboots, it's not a one-off issue. Rebooting into 3.16.0-17.23 works fine.
