[hsflinux] ACPI/APIC problem with POWEROFF after installing HSF driver.

for HDA modems, the HSF driver has to disable all the HDA related 
modules from the original kernel and it provides it's own version of 
these modules. In other words, it can affect a HDA sound device and it's 
great that in your case, it did solve a problem.

For the suspend problem, if you use the 'hsfstop' command in a root 
shell before suspending, does it solve the problem?

Why exactly do you think if could be an IRQ related problem?
