It fails to create a slab. There should be some of message above what I
can see that would indicate what went wrong.

Please try to reboot and specify "slub_debug" as a kernel parameter. If it
boots then send us the kernel log output. Must have something to do with
how the scsi slab is created in scsi_setup_command_freelist.
