it's always possible that it is a IRQ related problem but I find it 
strange that it was working right with the original HDA modules. If this 
is a bug with the HSF driver and we are able to reproduce it, it will 
probably be solved in a future version.

You could also try to boot with the 'acpi=off' kernel boot parameter as 
well to see if there is a difference.
