What hypercall was that? I see

		storvsc_log_ratelimited(device, loglevel,
			"tag#%d cmd 0x%x status: scsi 0x%x srb 0x%x hv 0x%x\n",
			scsi_cmd_to_rq(request->cmd)->tag,
			stor_pkt->vm_srb.cdb[0],
			vstor_packet->vm_srb.scsi_status,
			vstor_packet->vm_srb.srb_status,
			vstor_packet->status);

in your patch where `vstor_packet->status` is claimed to be a hypercall
status? I'd be surprised if the hypervisor concerned itself with
the details of visualized SCSI storage. The VMM on the host might and
should.

I'll look through the code to gain more confidence in my suspicion that
calling the SCSI virt storage packet status a hv status causd the
frustration with debugging, and if no counter examples found, will send
a patch to fix that log statement above.
