Bootup screenshot showing problem

I have an Areca ARC-1280ML RAID controller in my home server, and it appears
that something changed in kernel 5.16 causing the driver to hang with:

arcmsr0: abort device command of scsi id = 0 lun = 1
arcmsr0: abort device command of scsi id = 0 lun = 0
arcmsr0: abort device command of scsi id = 0 lun = 3
arcmsr: executing bus reset eh.....num_resets = 0, num_aborts = 3
arcmsr0: wait 'abort all outstanding command' timeout
arcmsr0: executing hw bus reset .....
arcmsr0: wait 'start adapter background rebuild' timeout
arcmsr: scsi bus reset eh returns with success
arcmsr0: abort device command of scsi id = 0 lun = 3
arcmsr: executing bus reset eh.....num_resets = 1, num_aborts = 4
arcmsr0: wait 'abort all outstanding command' timeout
arcmsr0: executing hw bus reset .....
arcmsr0: wait 'start adapter background rebuild' timeout
arcmsr: scsi bus reset eh returns with success

(this then repeats until system panics because it can't mount root)

When this happens, the card also stops responding on out-of-band network. With
kernel 5.15 there are no problems.

I normally run bcachefs kernels, but I also tested with regular 5.17.1 kernel,
where the same problem happens.
