I've tested "irqfixup" in the same situations. The behavior is just the
same as irqpoll: it fixes my machines, through 2.6.38. From .39 on, it
doesn't catch the bad irq.

I have tried looking for reports like this, in the BTS's of other major
distros. I don't see any -- it may be too early, as not many have
shipped a release with 2.6.39+, yet.
I have seen one user mention this problem, outside a BTS.
Interestingly, their machine needs "irqpoll" for a quite differe

Yes, it may be best to post the bug to LKML, since bugzilla.kernel.org

Dang! I fumbled the keyboard there and posted prematurely.
I may be near the limit of my skills on this one, but I'll try to learn
more. This hardware is (otherwise) serving well for me, so I'd be happy
to keep using it, if I can. I'm not in a position to say, right now,

Ok, did a bunch more building and testing. They cant' be exhaustive,

The config option that makes a difference is the sound driver for the

Things are a bit more complicated than I thought, and you should
disregard what I said in comments 12, 13, and 14. Apologies.
The regression appears dependent on the kernel configuration. As I was
building test images, I was shutting off many drivers and options that I
hoped were irrelevant , to

Edward,
I don't really have time to dig into this at the moment (maybe this
evening), but have you checked the revision history on
kernel/irq/spurious.c? That seems to be where the irqpoll stuff is
handled.
Cheers!

The last 2.6.38 was fine, and anything from that first .39 release

This issue appears to be an upstream bug, since you tested the latest

Hi Joseph and mfg. I have tested it with a daily kernel image, too,
and it has the same problems.
(I didn't know about the mainline builds; I was going to try building an
upstream kernel. So that was quicker, thank you.)
And I hoped to look at the kernel bugzilla, but it's still offline.
