I have several machines that need to boot with one of these options, and I see reports of this regression from multiple other users. The interrupts now generate the same errors seen without these kernel options, e.g.: irq 19: nobody cared (try booting with the "irqpoll" option) even though irqpoll, or irqfixup, is used. 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: commit d05c65fff0 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=d05c65fff0ef672be75429266751f0e015b54d94 I have a patch that fixes most of my machones, and the maintainer has accepted it: https://lkml.org/lkml/2011/11/2/260 Any testing of the current patch would be great. I wish I could say that's the end of it, but I have found configurations on my machines where a bad irq still goes uncaught, even with my patch. Focusing on those cases, it comes down to this patch: commit fa27271bc , genirq: Fixup poll handling http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=fa27271bc8d230355c1f24ddea103824fdc12de6 This patch changes the approach in multiple ways, and I haven't figured out where it drops the ball. I've toyed around with the changes, but have not produced a clear fix. I'll keep trying, and will be in touch with the maintainer again.
