Dear Thomas and other people,
After experiencing problems with many post 2.6.38 kernels with X when I used
Firefox to see any webpage that used some of the new HTML5 features (Firefox
freeze completely X and I could only log in remotely with SSH), I took some
time to see where things went wrong and, to cut a long story short, I
bisected the kernel and I found that a commit of yours was the first one
that introduced a problem with my system:

| fa27271bc8d230355c1f24ddea103824fdc12de6 is the first bad commit

| genirq: Fixup poll handling
|
| try_one_irq() contains redundant code and lots of useless checks for
| shared interrupts. Check for shared before setting IRQ_INPROGRESS and
| then call handle_IRQ_event() while pending. Shorter version with the
| same functionality.

Here I have the dmesg output slightly edited with the points that I think
that are the most relevant to the problem. Please note that my understanding
of devices/hardware is next to nothing and I may have cut important parts.

`----
I see that the commit in question is one in a long chain of the genirq
facelift. Could I help with getting this fixed for this desktop of mine?
Apparently, the rewrite/shorter version didn't preserve all the same
behaviour...
I hope that I did my homework right bisecting, recompiling, etc. the
kernel. If not, please advise.
I am willing to test with whatever you want me to.
Thanks, Rogério Brito.

Can you attach /proc/interrupts as well please.

Sure, I am attaching the contents of /proc/interrupts from both a kernel
that works and one that doesn't.
Please, advise if you want more information and how you would prefer me to
send them. I will do my best to get those to you.

It's been a week since I sent my first message. Did it get through?

Again, if you need any information, please let me know and I will do

Hi once again, but things are not good with any kernel past the
reworked IRQ stuff.

It seems that the radeon thing is just one of the manifestations of
the problem.
Today, I noticed another bad symptom, when I accidentally booted with
kernel 3.0 (I have many kernels in GRUB2): I printed a LaTeX document
with only 2 pages of pure text. My printer is an inkjet printer
connected via USB to my computer and it took about 6 minutes to print
those 2 pages. The printer head moved printing something, then it
paused a bit, then it printed some more, then it paused some more etc.
I just rebooted with 2.6.38 and the very same document was printed
in, like, 15 seconds...
So, is there anything that I could do to rectify this situation? I
can give you loads of dumps from here, as long as you tell me what
would be useful.
Thanks,

Well I was hoping Thomas would help debug this, but he's gone on
holidays, I'll try and take a look next week.
but I've no real idea about the irq subsystem.
Dave.

Thanks for the prompt reply. Should I file it on bugzilla? Just as a
reminder, the first problematic commit is
fa27271bc8d230355c1f24ddea103824fdc12de6: genirq: Fixup poll handling
As the MAINTAINERS file only lists Thomas as the responsible for the
IRQ subsystem, I'm still CC'ing linux-kernel, but I can bring the
discussion to any other mailing list, if applicable.
Thanks,
