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..] ...... --------------------------------------- i'm getting the same problem (although not sure if the dma status was the same) if i enable hardirq preemption turning acpi on/off doesn't change anything io/up apic is on (haven't tried disabling it) with hardirq preemption disabled in .config everything looks fine sofar (~5h ) ----------------------------- 666 root 16 -10 0 0 0 S 0.0 0.0 0:00.00 IRQ 17 670 root 15 -10 0 0 0 S 0.0 0.0 0:00.00 IRQ 14 673 root 15 -10 0 0 0 S 0.0 0.0 0:00.00 IRQ 15 711 root 25 0 0 0 0 S 0.0 0.0 0:00.23 khubd 712 root 16 -10 0 0 0 S 0.0 0.0 0:00.00 IRQ 21 ---------------------------- this puzzles me a bit aren't those hardirqs ? why are they listed as threads, in case i compiled with ---------------- [svetljo@svetljo rc2mm1]$ grep PREEMPT .config # CONFIG_PREEMPT_TIMING is not set CONFIG_PREEMPT=y CONFIG_PREEMPT_VOLUNTARY=y CONFIG_PREEMPT_SOFTIRQS=y # CONFIG_PREEMPT_HARDIRQS is not set ---------------- best, svetljo PS.
