Hello,

I got the following syslog message

Sep 27 22:03:52 zahn vmunix: Unhandled edge irq 7 (5 c7b0fec0)
Sep 27 22:03:56 zahn last message repeated 5 times

while using my Fritz!-ISDN-Card (which is on irq 7). System operation
was not affected.

The system is based on Dual-PentiumII, 233MHz,
Gigabyte GA-686LX2 motherboard. The kernel is compiled with
egcs-2.90.29 980515 (egcs-1.0.3 release)

Find the kernel configuration used at http://www.snafu.de/~zahn/autoconf.h

Complete boot messages are at http://www.snafu.de/~zahn/bootmsg.txt
Of interest may be this:
Sep 27 14:52:26 zahn vmunix: IO-APIC pin 0broken BIOS, changing pin 10 to edge
Sep 27 14:52:26 zahn vmunix: broken BIOS, changing pin 11 to edge
Sep 27 14:52:26 zahn vmunix: broken BIOS, changing pin 15 to edge

/proc/interrupts looks like this:
