2.6.4 works fine.

The ohci_hcd problem should be temporarily fixed by a recent patch to this list, from Greg KH (subject: [PATCH] USB: Eliminate wait following interface unregistration). This worked for me.

As for the snd_ modules, this is a different problem, which I am still experiencing. I have had it with both snd_emu10k1 and snd_intel8x0 - but it does not happen every time. I have experienced it on 2.6.5-rc2 and -rc3 (plus their -mm patches). rmmod hangs and doesnt respond to kill -9.

Is there any output I can capture to diagnose this?
