Hi Rafael,

same problem here, although I was able to resume system (it's basically Intel
machine) , but it was unusable - I was able to switch between terminals and see
output from kernel. So there was:
- Disabling irq #19;
- some kind of lock spinning on disk:
IDE interface: Intel Corporation 82801GBM/GHM (ICH7 Family) Serial ATA Storage
Controller IDE (rev 02)
but I can't provide more output of that lock now - no sign in logs.

I've made some successful suspend/resume all without sound card active without
problem. Those appear with sound card active, but I must take closer look - will
send info later.
