The PCM pointer callback sometimes returns invalid positions and this screws up the hw_ptr updater in PCM core. Especially since now the jiffies check is optional with xrun_debug, the invalid position is handled as is, and causes serious sound skips, etc. This patch simplifies the position-fix strategy in intel8x0 to be more robust: - just falls back to the last position if bogus position is detected - another sanity check for the backward move of the position due to a race of register update and the base-index update This patch is applicable also for 2.6.30.
