Bug#362708: acpi_cpufreq and snd_atiixp conflict



Package: linux-image-2.6.15-1-686-smp
Severity: normal


When acpi_cpufreq kernel module is loaded, alsa would randomly break. The
application accessing sound sometimes hangs and cpu usage gets 100%, and
sometimes it works fine. Multiple applications accessing sound at the same
time often causes the problem to appear, but a single application could too.
Without acpi_cpufreq loaded, alsa works perfectly fine with single or
multiple applications accessing sound at the same time.

I am not sure, though, if this is a problem with my acpi. This is a Toshiba
Satellite A70 laptop with atiixp chipset and Pheonix BIOS. The machine
shuts down properly but does not reboot. Reboot completes the shutdown but
stops there before actually turning off the machine or rebooting it. LEDs
stay on and I can hear the fan.

I used to use p4_clockmod scaling driver just fine. acpi_cpufreq could not
be loaded in previous kernels. This is the first kernel in which I managed
to load acpi_cpufreq, and it seems to work fine, except for the sound problem.
