The trace shows that it's __wait_on_page() that does the jumping, and it certainly shouldn't jump to xetup_x86_irq.. The only jump it does (apart from a schedule) is to start up the disk IO with "run_task_queue(&disk_tq)". It looks like some disk driver isn't setting up the task queues correctly or similar. Can you tell me (remind me - I'm sure I've heard it before) what block device drivers you use? (loop/scsi/ide/idecd etc..)
ide (RZ1000) scsi (53c810, with synch, fast, disconnect enabled) -- disk and tape sonycd
Just as a side note, be suspect to SCSI driver bugs/problems when you see this behavior. Recently I completely rewrote the Sparc SCSI driver, I saw very similar behavior. Wait queue's were being corrupted, weird ptrs being dereferenced in unlock_buffer() etc. and it turned out to be DMA overrun/underrun's happening in the SCSI driver.
