Quiet old butg, but it seems to be there again? My kernel is 3.13.0-45-generic #74-Ubuntu and I have to use IRQPOLL to keep harddisks from crashing and today, I got a crash again related to IRQPOLL. (Feb 19 04:51:02 mythtv kernel: [45426.291760] irq 18: nobody cared (try booting with the "irqpoll" option) Feb 19 04:51:02 mythtv kernel: [45426.358066] irq 19: nobody cared (try booting with the "irqpoll" option))
Seems, that this bug raises up again on actual kernel releases? Best regards QD -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/855199 Title: "irqfixup" and "irqpoll" broken since 2.6.39 Status in The Linux Kernel: Fix Released Status in linux package in Ubuntu: Fix Released Status in linux source package in Oneiric: Fix Released Status in linux source package in Precise: Fix Released Bug description: In all kernels since 2.6.39, the "irqfixup" and "irqpoll" options are no longer taking effect. 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, isolated two regressions, and submitted patches for each. The first bug effectively disabled the bad-irq handling routines, by a test condition be accidentally reversed. This is the commit where the regression arrives: commit d05c65fff0 , genirq: spurious: Run only one poller at a time http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=d05c65fff0ef672be75429266751f0e015b54d94 The maintainer has accepted my patch for that, and it's on its way into releases: it will be in Linux 3.2, and upcoming stable releases, likely 3.0.11 and 3.1.3. And it's marked as committed to Oneirc now. It's attached here, and is in Linus' tree at: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=c75d720fca8a91ce99196d33adea383621027bf2 That bug disabled irqfixup & irqpoll for everybody. But with that fixed, I had some machines where those kernel options still failed. I bisected that problem to here: commit fa27271bc , genirq: Fixup poll handling http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=fa27271bc8d230355c1f24ddea103824fdc12de6 I've submitted another patch, for that regression, and Linus merged it. Yay. So 3.2 should be good, and 3.0/3.1 updates in a bit -- it took a month, last time.
