Hallo!
Since two weeks I have a problem on my ThinkPad R31 running Debian with
the 2.6.12-1-686 kernel I am running since two months or so (do not
remember). The machine is a Pentium 3-M with 392 MB RAM and 3 Intel
USB-Hubs:
lspci
0000:00:1d.0 USB Controller: Intel Corporation 82801CA/CAM USB (Hub #1)
(rev 02)
0000:00:1d.1 USB Controller: Intel Corporation 82801CA/CAM USB (Hub #2)
(rev 02)
0000:00:1d.2 USB Controller: Intel Corporation 82801CA/CAM USB (Hub #3)
(rev 02)
Not always, but almost always, whenever I attach an USB device on the
BUS, I get such an error message (invariable for each time I got it!
Only the timestamp changes!) in syslog:

Nov 15 19:36:46 localhost kernel: Disabling IRQ #11
Nov 15 19:37:06 localhost kernel: i810_audio: drain_dac, dma timeout?
After that all devices on IRQ11 (cardbus, audio, ethernet) do not work.
I got the hint using boot parameters "pci=noacpi irqpoll" which did not
really work.
I tried changing the dimm on bank0 with that on bank1, I ran memtest on
each dimm separately and combined - the RAM is OK and the problem
persists (actually, there is a combination where memtest reboots but the
systems runs stable with USB not working).
I compiled a 2.6.14 kernel by myself and running it I get the same
error. Booting it with "irqpoll" option still gives me the same error
message, but at least audio, ethernet and so on continue working as well
as the USB devices.
What I have also tried, to plug the notebook into the port replicator
and attach the devices (one at the time) to the USB-port of the
replicator - system runs very stable (2.6.12-1-686 kernel)!
lsusb
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000
I found out these three busses are used one for the Ultrabay, one for
the port-replicator and one for the two "internal" ports.
Now, I would like to know what the hell is going on. It does not look
like a driver-problem to me, as the same driver handling the US-BUS 2 is
the same handling the US-BUS 1. On the other hand, how could a defective
USB-hub crash the interrupt-handler?
I tried now to reproduce the error once again to dump /proc/interrupts -
but this time it does not work. As I said, it happens most of the times,
not always. I will post a dump of
Maybe one of You can help analysing the problem?
Saluti!
