Bob, Alex,
(or anybody else with a SIS-961 that now requires acpi=noirq),

I need some info to find out why your system recently broke.

Please open a bug here and attach the info,
http://bugzilla.kernel.org/enter_bug.cgi?product=ACPI
or just e-mail it to me and I'll open a bug for you.

Need the complete dmesg and /proc/interrupt from the most recent ACPI
enabled kernel that worked properly -- I guess -bk6 worked okay?

Any chance you can boot with "debug" and capture the console messages
from the failure? If no, then the complete dmesg of the latest kernel
with "acpi=noirq" is the next best thing.

output from lspci -vv

output acpidmp available in /usr/sbin/, or in pmtools:
http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/utils/

thanks,
-Len

ps. would also be good to verify you're running an up-to-date BIOS.

pps. taking a wild guess, can you try backing out this patch?
