    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.

    -Jacek
