I have these log entries on my IBM Thinkpad T40. More of them occur
during heavy networking.

As adviced by Stefan in #65 I checked the IRQ settings in BIOS. (I
believe they were under PCI settings). They all were on IRQ11, too. And
I changed all of them to Auto. Additionally I turned off peripherials,
which I never use (serial, parallel and infrared).

The effect was that the following 4 devices switched from IRQ 11 to IRQ
5 (checked using the lspci command)

- 00:1f.3 SMBus: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M)
SMBus Controller (rev 01)

- 00:1f.5 Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM
(ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 01)

- 0:1f.6 Modem: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M)
AC'97 Modem Controller (rev 01)

- 02:00.1 CardBus bridge: Texas Instruments PCI1520 PC card Cardbus
Controller (rev 01)


The fatal interrupts for the ipw2100 (which is still on IRQ 11) do still appear. Maybe they appear somewhat less frequently than before. I have not made any really statistics.

Kubuntu Lucid 10.04 with all updates.
