Subject: Re: [Alsa-devel] HDA Intel sound driver fails on Acer notebook

FWIW, using pci=noacpi seems to break the USB controller on this laptop.  
I get "device not accepting address xx, error -110.

In addition, neither the onboard nor the wireless NIC work anymore with
this option.  For the onboard, you see that the link is up, but then
get "NETDEV WATCHDOG: eth0: transmit timed out."

acpi=off is worse - the boot hangs trying to load acpi/thermal.ko.

I've tested with both 1.0.13 and and 1.0.14rc1.  I don't get exactly
the same kernel logging (I'm using a Debian 2.6.18 kernel), but kern.log
contains:

Dec 19 17:39:43 maus kernel: : hda_codec: invalid dep_range_val 0:7fff
Dec 19 17:39:43 maus kernel: ALSA /home/tony/alsa-driver-1.0.14rc1/pci/hda/hda_codec.c:216: hda_codec: invalid dep_range_val 0:7fff

Thanks in advance for any assistance.  I hope you enjoyed your
vacation.

Thanks,
tony
