ALSA as a timer source is broken for me on kernels 2.6.34 onwards

Description

In 2.6.33 I can play all my audio and video files just fine.

In kernels 2.6.34 and .35 I have severe problems playing all my files: with -ao ALSA mplayer randomly skips large chunks of source data without playing it.

Linux kernel bug report is filed here: https://bugzilla.kernel.org/show_bug.cgi?id=16300

Probably someone can spot the problem in strace output.

Note that ALSA log has this problem.

This problem only occurs with:

04:00.0 Generic system peripheral [0841]: Creative Labs SB Live! EMU10k1 (rev 07)

It doesn't occur with:

HDA Intel at 0xfbdf8000 irq 44 (Codec: VIA VT1718S)

It's a kernel bug.
