Have you got CONFIG_DETECT_SOFTLOCKUP turned on?  With any luck that
will at least pinpoint where the code has locked up.  Otherwise it's
going to be a case of bisection via printk().

A contrast and compare of the hardware initialisation on initial boot
compared to coming out of suspend might identify the problem.  If the
playback is working it's *probably* something missing in the CPU init
that's specific to capture.
