Hopping on this thread as I have the exact same issue. I have spent significant
time attempting to debug this and will share what I've found so far. I have two
nearly identical systems HPE dl180 g10 with p816i controllers. One has SATA
disks, the other SAS. Only the system with SAS disks seems to be affected. Only
a zfs scrub triggers this panic - the system is otherwise stable. The hardware
has been verified OK by successfully completing a scrub under CentOS 8.4 with 0
errors. I have been able to reproduce this on every OS/driver/firmware
combination up to and including:
FreeBSD 13.0
Microsemi driver v4130 (8/5/2021)
HPE SmartArray Firmware 3.53
I'm willing to help debug as this is a 100% reproduceable issue - sometimes
within first 1% of scrub progress, but never more than 8-9%.
