The out: block\nthen re-issued qla2x00_get_firmware_state() because rval != QLA_SUCCESS,\ndefeating the chip-down/EEH-busy guards and issuing a mailbox command\n(outside optrom_mutex) during ISP reset or PCI error recovery, which can\nhang the adapter. It also turned a normal in-lock mailbox failure into a\nsecond unsynchronized mailbox attempt.\n\nMake the out: fallback only mark the firmware state as unknown. The\nmailbox is now issued at most once, inside optrom_mutex, and only when\nthe chip is up and not EEH-busy.",
