[Bug 855199] Re: 2.6.39 and later have lost "irqfixup" and "irqpoll" functionality
** Description changed:
- I have several similar HP boxes that boot with IRQ errors, for the USB
- subsystem, like this:
+ In all kernels since 2.6.39, the "irqfixup" and "irqpoll" options are no
+ longer taking effect. I have several machines that need to boot with
+ one of these options, and I see reports of this regression from multiple
+ other users. I do not know whether these options will fail for all
+ cases, or if some unknown hardware configurations are out there
+ continuing to work.
+
+ The interrupts generate the same errors seen without these kernel
+ options, e.g.:
irq 19: nobody cared (try booting with the "irqpoll" option)
- ...
- So I have indeed always used the "irqpoll" kernel argument, and that has
- fixed the USB performance problems.
+ even though irqpoll, or irqfixup, is used.
- Under 2.6.39 and 3.0, the irqpoll fix has stopped working. The logs say
- "try booting with the 'irqpoll' option", though they also show that
- argument was present.
+ The Linux irq code was reworked during the 2.6.39 cycle. I have gone
+ through the patches, and this is the commit where the regression
+ arrives:
- Here is some context on the IRQ errors:
+ genirq: spurious: Run only one poller at a time
- These machines all have a PCI-E x16 slot, for video cards. They only
- have the IRQ problems when that slot is used; if I revert to onboard
- video, they go away. When I do use a video card, as I'd prefer to do,
- the errors come regardless of which card, whether it is ATI or Nvidia,
- with open or proprietary drivers. "Irqpoll" has always taken care of
- them, until 2.6.39 arrived.

- At first I was uncertain whether it was just a problem with the boot
- argument taking effect, but now I have seen the logs do say "Misrouted
- IRQ fixup and polling support enabled".
