Hi All,

I'm having basically the same issue on my Asus M6N though with different
drivers.  I'm running Fedora Core 2 with a vanilla 2.6.7 kernel.  In my
case snd-intel8x0 and ipw2100, which both share IRQ 11, work ok for a
short while after an S3 resume but then freeze up and refuse to respond
until I unload and reload them.  I think the interrupts not incrementing
is just a symptom of the problem rather than the cause.  A reliable way
to reproduce it is to play music while either transferring a big file or
doing a ping -f.  This usually knocks them out pretty fast however it's
not at all consistent about the length of time they will work after a
resume.  

After reloading both of them, either one will work by itself but as soon
as I try to use them together both freeze again, and this time they
freeze pretty much immediately.  I noticed that PCI registers are set
differently after the machine comes back from S3 so I tried setting them
back manually but that did not fix the problem either.  There are some
that actually refused to be set so maybe that has something to do with
it.  I am attaching outputs of lspci -xxx and lspci -vv from a pre-S3
state and post-S3 if somebody thinks they might be helpful.  I also
tried alternate drivers for both devices (i810-audio and ndiswrapper)
with similar results.

Also, after an S3 resume, I only see 'inu' in yellow on black letters on
the screen, the ASM in wakeup.S is pretty impenetrable to me so I don't
know if this indicates a problem or not.  My laptop also does not reboot
properly after an S3, just hangs there after saying it's about to
restart, but again I'm not sure it that's related or not.

Thanks in advance for any help, and if I should provide any further
information please let me know.
