Distribution: AlmaLinux 8.8
Kernel Version: 4.18.0-477.13.1
Architecture: x64
OpenZFS Version: 2.1.5-1

Intermittent communication dropouts are occurring with SSD drives that are attached to Marvell 88SE9235 SATA controllers via Marvell 88SM9705 port multipliers. The SSD drives are M.2 form factor and are typically models from WD or SanDisk. When the issue occurs, communication with all SSD drives (5) connected to port multiplier is lost and the driver performs recovery steps in order to re-establish connection with the SSD drives. This results in ZFS I/O errors being reported from zpool status. Multiple events with unsuccessful recovery steps by driver can lead to pool suspension.

The issue occurs with both small and large I/O workloads, though usually takes longer to manifest with small I/O workload.

The issue does not occur with older version of CentOS and ZFS running on same hardware. Details:
Distribution: CentOS 7.9
Kernel Version: 3.10.0-1160.15.2
Architecture: x64
OpenZFS Version: 0.8.6-1

Typically, the ZFS pools in use on AlmaLinux were created in CentOS. Creating the pools in AlmaLinux did not resolve issue.
Have tried the following, in different combinations:

Disabling NCQ
Lowering SATA speed to 3.0
Upgrading ZFS to 2.1.13
Changing SATA power management from max_performance -> medium_power
Changing I/O scheduler from None -> mq-deadline
Change max_sectors_kb -> 512

The issue can be reproduced as follows:
Small I/O workload: Boot-up system w/ apps that generate small sustained I/O load on the ZFS pool and let it run w/o interaction
Large I/O workload: Use fio to generate heavy I/O workload on ZFS pool
