It was reported here: http://lists.debian.org/debian-powerpc/2005/01/msg00781.html I didn't personnaly report it because it was hard to track it down; it'd happen about once in twenty resumes (more often when you're in a quiet place with strangers around, evidently, according to Murphy's law), and nothing unusual appeared in dmesg (even with SND_DEBUG, which doesn't debug much on ppc anyway).
