X60/T60 is known to be often broken regarding the communication
between the controller and the codec chip. When this kind of thing
happens, the driver tries to switch to a single-shot I/O without using
ring-buffers and IRQs, and even in such a mode, the communication gets
broken. FWIW, it doesn't happen on other machines with HD-audio, so
it's fairly specific to X60/T60. No idea why.
What about Acer Aspire 5102?

This is a different problem.
A known workaround is to provide probe_mask=1 module option.

BTW, does this happen on the latest linus git tree? (rc4 may work,
though)

If yes, could you try the patch below?


I can't easily test 2.6.21-rc, but "probe_mask=1" works on 2.6.20.4, which spews
errors without that. Should I try your patch on 2.6.20?
