Subject: Weird IO-APIC mappings under Linux-2.2.17smp (fwd)

Dear linux SMP team,
I am sending this at the suggestion of my kernel, which prints the
following message at boot time:
WARNING: unexpected IO-APIC, please mail
to linux-smp@vger.rutgers.edu
I think this could very well be the cause of the problems I've been
having. My dual-pIII Dell Precision 420 seems to boot and work just fine
using SMP; however, the onboard sound card, a Crystal Audio CS4614 (which
should work with the freeOSS cs4232 driver) seems to get mapped to a funny
place... which is not so funny, since I can't seem to get sound working on
this box. According to the BIOS, the sound card should take IRQ 5, and
indeed, when I boot a single-processor kernel, it shows up as IRQ 5.
However, in SMP mode it seems to take IRQ 18. I am unable to load the
driver for it, despite passing insmod what seem to be
universally-agreed-upon settings for io, dma, and dma2 (as well as the
correct IRQ setting). I always get the following message:
/lib/modules/2.2.17/misc/cs4232.o: init_module: Device or resource busy
Hint: this error can be caused by incorrect module parameters, including
invalid IO or IRQ parameters
/lib/modules/2.2.17/misc/cs4232.o: insmod
/lib/modules/2.2.17/misc/cs4232.o failed
/lib/modules/2.2.17/misc/cs4232.o: insmod cs4232 failed
This is quite frustrating. I hope it is a result of weird APIC mapping,
although the fact that I can't get it working using a single-processor
kernel, either, is not encouraging.
In any case, since I have been warned I figured I'd pass the output of
dmesg on to you. If there is any other useful information I can provide,
please feel free to ask. If you can help me get my sound card working,
terrific; if that is completely unrelated to the IO-APIC mapping issue,
oh, well, at least I (hopefully) provided you with something useful. :)
Attached are the outputs of dmesg, /proc/pci and lspci, respectively.
Please email me if there is any more information you require.
Thanks!
