No idea how to proceed. This sounds like you may have a problem with this patch: commit d5038a13eca72fb216c07eb717169092e92284f1 Author: Johannes Thumshirn <jthumshirn@xxxxxxx> 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.
