I've found this crash to be repeatable, and it exists with both the latest
prerelease and cvs. When running swfplayer from the flash-0.4.10 package
(available from http://www.swift-tools.com/Flash) the driver oopses,
leaving the pcm device unusable and impossible to unload.
The output of ksymoops is as follows
