That problem is apparently caused by 9dc704dcc09eae ("scsi: aacraid:
Reply queue mapping to CPUs based on IRQ affinity") [v6.4-rc7]. That
commit despite a warning of mine to Sasha recently made it into 6.1.53
-- and that way apparently recently reached more users recently, as
quite a few joined that ticket.
Is there a full kernel log for this hanging system?
I can only see snippets in the ticket.
And what does /sys/class/scsi_host/host*/nr_hw_queues show?
Thanks,
John
