Hi Aaron - The Oneiric updates still don't contain my second patch, despite Launchpad marking it 'fix released'. Maybe that machine needs it, like some of mine do? It's the second attachment here, in 3.2-rc4 and later, and yesterday's stable updates, 3.0.13 and 3.1.5. Because of the latter, I think it should be in Oneiric with their next stable update.
If you can try it, maybe with the mainline builds, here, http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.0.13-oneiric/ I'd certainly be interested to hear. Thanks. :) -- You received this bug notification because you are a member of UBUNTU - AL - BR, which is subscribed to Mythbuntu. https://bugs.launchpad.net/bugs/855199 Title: "irqfixup" and "irqpoll" broken since 2.6.39 Status in The Linux Kernel: Fix Committed Status in Mythbuntu, Ubuntu derivative focused upon MythTV: Fix Committed 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.
