$ cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.9 (Sun May 29 07:31:02 2005
UTC).

I see that the kernel has version 1.0.9.  The bug was (probably) fixed in 1.0.9a.

/usr/share/doc/alsa-base/changelog.gz:
Changelog between 1.0.9 and 1.0.9a releases
  + PCM Midlevel
    - Fix races between PCM drain and other ops

It seems that the ALSA drivers in the kernel need to be updated.
