I guess you don't use virtio-scsi/virtio-blk since both run at blk-mq mode at default, even though without d5038a13eca72fb.
Boot logs and so on can be found here:

The ramdisk is unfortunately not linked through the UI, though we don't get that far.
And a full LAVA boot log from my lab http://lava.streamtester.net/scheduler/job/138067
QEMU command line here: http://lava.streamtester.net/scheduler/job/138067#L75
And a LAVA job definition, which includes the url of the ramdisk and kernel: http://lava.streamtester.net/scheduler/job/138067/definition#defline76
Thanks for the sharing!
I can reproduce this issue with above script/initrd/kernel config, and looks the issue disappeared after 'scsi_mod.use_blk_mq=0' is passed.
Not see such issue with zero-day ktest config.
Looks a bit weird, given SCSI_MQ is nothing related with ramdisk.
Seems related with sr:
1) with scsi-mq [ 2.808204] ata2.01: NODEV after polling detection [ 2.809807] ata2.00: ATAPI: QEMU DVD-ROM, 2.5+, max UDMA/100 [ 2.827377] scsi 1:0:0:0: CD-ROM QEMU QEMU DVD-ROM 2.5+ PQ: 0 ANSI: 5

We may need to take a look at recent SCSI change.
Thanks, Ming
