Subjectqla2xxx: frequent total lockups (2.6.8, 2.6.9-rc{1-mm5,2})
Hi!

I'm currently setting up a new Dual Opteron box (Tyan Transport
GX28) equipped with a QLogic QLA2340 fibre channel HBA.

As soon as there is I/O load on the HBA, I start seeing

qla2300 0000:01:03.0: qla2xxx_eh_abort: cmd already done sp=0000000000000000

messages every few seconds, eventually leading to complete system lockups after
several minutes up to several hours, due to kernel NULL pointer dereferences
in qla2x00_cmd_timeout().

I've tested and reproduced the error on the following kernels, all
compiled for x86_64.
2.6.8.1
2.6.9-rc1-mm5 (with dma_fixups patch posted by Andrew Vasquez on 13.9)
2.6.9-rc2

Attached are a complete 2.6.9-rc1-mm5 log from boot to crash as well as
two 2.6.9-rc2 crash dumps with only the post-boot messages.

The .config used and the complete logs can be found at
http://www.cip.ifi.lmu.de/~bolzer/tmp/qla-problem/

Without any I/O on the HBA (nothing mounted), I have yet to capture a
crash, but the driver still ocasionally reports
qla2300 0000:01:03.0: cmd_timeout: LOST command state = 0x6

Any help would be greatly appreciated. If there are any tests I could
run, just let me know.

Bootdata ok (command line is root=/dev/sda3 ro console=ttyS0,115200n8 console=tty0 )

PCI: Using ACPI for IRQ routing
** PCI interrupts are no longer routed automatically. If this
** causes a device to stop working, it is probably because the
** driver failed to call pci_enable_device(). As a temporary
** workaround, the "pci=routeirq" argument restores the old
** behavior. If this argument makes the device work again,
** please email the output of "lspci" to bjorn.helgaas@hp.com
** so I can fix the driver.
