Before this I was happily using 2.6.8-rc3-O5. I tried booting with acpi=off but was unable to enter my user name at the login prompt, it just hung with no response to sysreq. I also tried turning off irq threading for that irq but it made no difference. There is one drive on the secondary channel of this Promise TX133. This is what appears in the log after a minute or two of using the drive. hdg: dma_timer_expiry: dma status == 0x24 PDC202XX: Secondary channel reset. hdg: DMA interrupt recovery hdg: lost interrupt hdg: dma_timer_expiry: dma status == 0x24 PDC202XX: Secondary channel reset. hdg: DMA interrupt recovery hdg: lost interrupt hdg: dma_timer_expiry: dma status == 0x24 PDC202XX: Secondary channel reset. [..many repeats..] It sometimes recovers but it immediately happens again. This leaves apps touching that drive stuck in an un-killable D state and eventually I have to reboot.
