Qlogic isp1040 with 2.4.21-rc1 (x86): driver won't load

[Zack Weinberg]

I am trying to use a Qlogic isp1040 board with 2.4.21-rc1 (x86).
lspci says:

00:09.0 SCSI storage controller: QLogic Corp. ISP1020 Fast-wide SCSI (rev 05)
        Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV+ VGASnoop-
                 ParErr- Stepping- SERR- FastB2B-
        Status: Cap- 66Mhz- UDF- FastB2B- ParErr- DEVSEL=medium
                >TAbort+ <TAbort- <MAbort- >SERR- <PERR-
        Latency: 32, cache line size 08
        Interrupt: pin A routed to IRQ 5
        Region 0: I/O ports at b800 [size=256]
        Region 1: Memory at e0000000 (32-bit, non-prefetchable) [size=4K]
        Expansion ROM at <unassigned> [disabled] [size=64K]

I believe that qlogicisp.o is the correct driver for this board.  When
I try to load it, most of the time I get these error messages:

isp1020 : entering isp1020_detect()
PCI: Found IRQ 5 for device 00:09.0
isp1020 : entering isp1020_init()

qlogicisp : loading risc ram
qlogicisp : verifying checksum
qlogicisp : executing firmware
qlogicisp : about firmware failure [4001]
isp1020 : leaving isp1020_detect()

This is with RELOAD_FIRMWARE, DEBUG_ISP1020, and DEBUG_ISP1020_SETUP
set to 1 in qlogicisp.c, and additionally with the "about firmware
failure" printk augmented to print the error code.  Code 4001 is
INVALID_COMMAND according to the list of mailbox status codes, which
seems decidedly odd.

Sometimes I get a different failure mode instead:

[repeat until machine rebooted]

Code 4005 is COMMAND_ERROR.  I am not sure what conditions trigger
this second failure mode; it *might* be "there's a powered-up device
other than the HBA on the SCSI bus."

Other information: The card is detected by the system BIOS, and the
adapter BIOS configuration utility (Fast!somethingorother) works.
When I've got the only other device on the bus (a DLT drive) turned
on, a bus scan from the adapter BIOS sees it.  However, the DOS-based
flash update utility I downloaded from Qlogic's web site insists that
there are no isp1xxx cards installed in the computer.

Any advice would be helpful.  Please cc: me on replies.
