The firmware stops responding to mailbox commands shortly after system boot is done. That also triggers an EEH on pseries machine and driver doesn't handle the EEH properly because firmware is effectively not available. I disabled eeh inside the guest as it caused a deadlock on the host kernel. The issue is fixed in linux-next by the commit edbd56472a63 ("scsi: qla2xxx: qla2x00_alloc_fw_dump: set ha->eft"). I think it should be included to 5.3 if possible. It can be cherry-picked cleanly to master. The logs of 5.3-rc8 (bad.log) and 5.3-rc8 with edbd56472a63 (good.log) are applied. -- You are receiving this mail because: You are watching the assignee of the bug.
