This does not look to be a Debian kernel, are you able to reproduce
the issue with the kernel provided in Debian? If so, does it happens
with the upstream kernel? And as I see a report here
https://github.com/LinearTapeFileSystem/ltfs/issues/484
this is a proxmox provided kernel.

But this does not look that it is specific to Debian kernel, so can
you please approach upstream as per:

./scripts/get_maintainer.pl ./drivers/scsi/pm8001/
Jack Wang <jinpu.wang@cloud.ionos.com> (supporter:PMC SIERRA PM8001 DRIVER)
"James E.J. Bottomley" <James.Bottomley@HansenPartnership.com> (maintainer:SCSI SUBSYSTEM)
"Martin K. Petersen" <martin.petersen@oracle.com> (maintainer:SCSI SUBSYSTEM)
linux-scsi@vger.kernel.org (open list:PMC SIERRA PM8001 DRIVER)
linux-kernel@vger.kernel.org (open list)

Please keep us in the loop with updates.

Regards,
Salvatore
