Package: linux-2.6
Version: 3.0.0-3
Severity: normal

Dear Maintainer,
when trying to figure out which kernel module might be using IRQ 3 in my Intel D525MW-based system by calling "cat /proc/interrupts", I get the reply "Killed" on the console, and the messages from [ 916.033769] onwards show up in the kernel log. When calling "cat /proc/interrupts" a second time, the system freezes completely, i.e. it ceases reacting on keystrokes an renders itself inresponsive over the network.
Background: I'm trying to get lirc_serial running using the board's internal serial connector (port 0x02f8, IRQ 3). However, although I disabled /dev/ttyS1 using "setserial /dev/ttyS1 uart none" (which by "setserial -g /dev/ttyS1" gets confirmed to be in effect), lirc_serial complains about port 02f8 being already in use (see [ 30.600691]) and IRQ 3 being busy ([ 34.175622]). Interestingly, "cat /proc/ioports" claims the port in question to be unused (see below), and as for IRQ 3, well... that's the cause for this bug report. 

Regards --

  Torsten
