Description Horst H. von Brand 2007-10-01 15:06:28 EDT
Description of problem:
After a while using my USB mouse the kernel complains it is disabling IRQ #18,
and the mouse (almost) stops working. Pluggig the mouse into another USB port
makes it work again.

Version-Release number of selected component (if applicable):
kernel-2.6.23-0.214.rc8.git2.fc8 (dual-core i686)

How reproducible:
Need to have the mouse plugged in a few hours, after that it shows up.

Steps to Reproduce:

3.

Please post full dmesg, plus contents of /proc/interrupts (a) shortly after
booting and (b) after IRQ 18 gets disabled.
Comment 3 Horst H. von Brand 2007-10-05 22:08:16 EDT
Seems to have gone now (kernel-2.6.23-0.217.rc9.git1.fc8).

Comment 9 Horst H. von Brand 2008-01-11 08:26:06 EST
Oops, didn't post the comment...

The problem showed up again some kernel revisions back. The attachments #4
through #8 are recent.

Toshiba Tecra A7 SP2022 (dual core i686), kernel-2.6.24-0.138.rc7.fc9
Comment 10 Horst H. von Brand 2008-01-14 07:50:29 EST
Still the same with kernel-2.6.24-0.150.rc7.git4.fc9, but it seems to take a bit
longer to trigger now.
Comment 11 Horst H. von Brand 2008-01-31 17:25:27 EST
Still the same with 2.6.24-7.fc9.i686 and 2.6.24-9.fc9.i686
Comment 12 Chuck Ebbert 2008-01-31 18:22:46 EST
Some unknown device is sending intterupts to IRQ 18.

You can use "noirqdebug" to work around this.
Comment 13 Horst H. von Brand 2008-03-08 22:10:11 EST
Fixed again (?), kernel-2.6.25-0.95.rc4.fc9.i686 (perhaps a bit earlier)
Comment 14 Horst H. von Brand 2008-03-09 12:48:27 EDT
Nope. kernel-2.6.25-0.95.rc4.fc9.i686 
It looks like this is one of the USB hubs. When the message shows up and my USB
mouse is plugged into the rear USB (which goes south when the message shows up),
the machine freezes. No mouse, no reaction to the keyboard.
Comment 15 Horst H. von Brand 2008-05-05 17:00:42 EDT
It is working OK now (kernel-2.6.25-14.fc9.i686, and several earlier ones,
startint with -rc1 I believe).

Can be closed.
