Hi,

By fickle I mean that when modprobing hda-intel module sometimes it 
works fine and others cannot get audio although the system seems to 
always recognize the card, and yes, I'm always using probe_mask=0x02 option.

Actually, about one of five times I can successfully load the module. As 
I said the first patch doesn't affect, it has been only the casualty 
that made me believe it did something.

When module loads successfully I can see in dmesg

HDA Intel 0000:05:00.0: PCI INT A -> GSI 38 (level, low) -> IRQ 38
hda_intel: probe_mask set to 0x2 for device 1102:0018
hda-intel: Invalid position buffer, using LPIB read method instead.

or:

HDA Intel 0000:05:00.0: PCI INT A -> GSI 38 (level, low) -> IRQ 38
hda_intel: probe_mask set to 0x2 for device 1102:0018
hda-intel: spurious response 0x0:0x0, last cmd=0x000000
hda-intel: Invalid position buffer, using LPIB read method instead.


And when the module doesn't load properly

HDA Intel 0000:05:00.0: PCI INT A -> GSI 38 (level, low) -> IRQ 38
hda_intel: probe_mask set to 0x2 for device 1102:0018
hda-intel: spurious response 0x0:0x0, last cmd=0x000000
hda-intel: azx_get_response timeout, switching to polling mode: last 
cmd=0x107f0d00
hda_intel: azx_get_response timeout, switching to single_cmd mode: last 
cmd=0x107f0d00
__ratelimit: 28 callbacks suppressed
