For any SCSI command, if the driver receives
IOC status = SCSI_IOC_TERMINATED and log info = 0x32010081 then
that command will be completed with DID_RESET host status.
The definition of this log info value is

Firmware will provide this log info value

The 'sd' driver is calling scsi_mode_sense() to figure out
internal details. But scsi_mode_sense() never checks for
any pending unit attentions, so we're getting annoying error
messages like:
MODE SENSE: unimplemented page/subpage: 0x00/0x00
and a possible wrong decision for device cache handling
Log the ALUA state change unit attention correctly with
the message log and emit an event to allow user-space
tools to react to it.

As scsi_mode_sense() is now retrying for any UAs it needs
potentially several retries to clear any UA status.
So increase the number of retries to at least 5.

The commit bcdb247c6b6a1f3e72b9b787b73f47dd509d17ec "sd: Limit transfer length"

of SBC4, this value is only supposed to apply to a small subset o
Looking at this closely, I didn't get the SDEV_UA text

The mpt2sas driver crashes if the BIOS does not set up at least one
memory I/O resource. This failure can happen if the device is too
slow to respond during POST and is missed by the BIOS, but Linux
then detects the device later in the boot process.
