I got the same bug this morning. Untainted 2.4.19 vanilla kernel.
I just noticed it because my kernel was creating Zombies ~10 hours
later.

My system: Debian unstable, P2 Celeron (Mendocino), ext3, bttv card,
lirc 0.6.5 and ati.2 driver from gatos.sf.net installed (does not
require kernel modules).
