Subject: 2.6.18: hda_intel: azx_get_response timeout, switching to single_cmd
 mode...

I have a ThinkPad X60 which uses the Intel 82801G HDA audio chip.  This 
used to work for me, but lately (sometime during 2.6.18-rcX series) it 
stopped working - programs trying to use it tend to just block forever 
waiting for /dev/dsp.

The only obvious symptom is:

    hda_intel: azx_get_response timeout, switching to single_cmd mode...

appearing in the kernel log when booting.

Details attached.  The dmesg output is for the FC6 distro kernel 
2.6.18-1.2689.fc6PAE, but I see the same symptoms with 2.6.18-mm1.
