These logs are showing three very different crashes:
1. Null dereference in bio_integrity_advance() during SCSI request
completion (odxu4a-oops.log, odxu4a-swap-panic.log)
2. WARN at the bottom of rcu_check_callbacks() (odxu4a-swap-trace.log)
3. Null dereference in xhci_irq() (odxu4a-swap-panic-4.13.log)
They all seem to be associated with initialisation of USB host and
device drivers, but none of them are obviously related to this bug
report. So I think these should be treated as 3 new bugs.
