--- Comment #3 from Roman Bolshakov (r.bolshakov@yadro.com) ---
Hi Martin,

I can't tell for sure, because f8f97b0c5b7f7 introduces a regression fixed in
1710ac17547ac8b ("scsi: qla2xxx: Fix read offset in
qla24xx_load_risc_flash()"). 

Here's the possible timeline:
1. f8f97b0c5b7f7 ("scsi: qla2xxx: Cleanups for NVRAM/Flash read/write path")
introduces a regression which prevents successful ISP firmware checksum
validation and kernel panics shortly after.
2. a28d9e4ef997 ("scsi: qla2xxx: Add support for multiple fwdump
templates/segments") introduces a regression which causes EEH and system lockup
on POWER8 or makes firmware unavailable (this bug).
3. 1710ac17547ac8 ("scsi: qla2xxx: Fix read offset in
qla24xx_load_risc_flash()") fixes  f8f97b0c5b7f7 but the fix depends both on #1
and #2.
4. edbd56472a63 ("scsi: qla2xxx: qla2x00_alloc_fw_dump: set ha->eft") fixes
a28d9e4ef997. 

It's not possible to bisect between #1 and #3 because of the panic introduced
in #1. And firmware works reliably only after #4.

And I think it's important to include your fix into 5.3, otherwise qla2xxx is
broken in the release.

Thanks,
Roman
