Subject: Re: Linux 2.6.30-rc1 boot failure on ia64 w/ QLA12160.  Bisected.

On and ia64 system with a QLA12160 adapter, my boot fails with:

qla1280: QLA12160 found on PCI bus 0, dev 3
qla1280 0001:00:03.0: PCI INT A -> GSI 61 (level, low) -> IRQ 61
scsi(0): Enabling SN2 PCI DMA dual channel lockup workaround
qla1280 0001:00:03.0: firmware: using built-in firmware qlogic/12160.bin
qla1280_mailbox_command: Command failed, mailbox0 = 0x0007, mailbox_out0 = 0x4003, istatus = 0x6000
m0 4003, m1 b141, m2 5555, m3 aa55
m4 55aa, m5 a5a5, m6 5a5a, m7 2525
scsi(0): RISC checksum failed.
scsi(0): initialize: pci probe failed!
qla1x160: Failed to initialize adapter

I did a git-bisect and narrowed it down to:

When I revert that commit from the 2.6.30-rc1 revision, I get a bootable
system.

Thanks,
