This sounds like you may have a problem with this patch:
commit d5038a13eca72fb216c07eb717169092e92284f1
Author: Johannes Thumshirn <jthumshirn@suse.de>
Date: Wed Jul 4 10:53:56 2018 +0200
scsi: core: switch to scsi-mq by default
To verify, boot with the additional kernel parameter
scsi_mod.use_blk_mq=0
Which will reverse the effect of the above patch.
We already have one report of this patch causing boot failures:
https://marc.info/?t=153305327000002
So I've added linux-scsi to see if they want any more information.
