Comment 1 Bill Nottingham 2002-07-01 18:52:43 UTC 
Does the bug persist without any of those drivers loaded since you boot?
Comment 2 Ricardo Ariel Gorosito 2002-07-02 03:04:00 UTC 
I'll test this tomorrow (today I can't boot).
FYI: With 2.4.18 (Linus) and those drivers loaded, system work fine.
Comment 3 Arjan van de Ven 2002-07-03 11:30:54 UTC 
This is a KNOWN nvidia bug.
This page_alloc bug is the typical signature of nvidia's module corrupting
memory....
