https://bugzilla.kernel.org/show_bug.cgi?id=204815 Bug ID: 204815 Summary: qla2xxx: firmware is not responding to mailbox commands Product: SCSI Drivers Version: 2.5 Kernel Version: 5.2-rc1 up to 5.3-rc8 Hardware: PPC-64 OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: QLOGIC QLA2XXX Assignee: scsi_drivers-qla2xxx@xxxxxxxxxxxxxxxxxxxx Reporter: r.bolshakov@xxxxxxxxx Regression: No Created attachment 284925 --> https://bugzilla.kernel.org/attachment.cgi?id=284925&action=edit firmware times out on 5.3-rc8 I'm using QLogic HBAs (QLE2560 and QLE2742) inside pseries guests on ppc64le/POWER8 hypervisor and they are not usable since commit f8f97b0c5b7f7 ("scsi: qla2xxx: Cleanups for NVRAM/Flash read/write path"). 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.
