Back again with another oops, which looks suspiciously similiar to the one i posted some days ago (https://listman.redhat.com/pipermail/ext3-users/2002-May/003587.html).

Now i'm running 2.4.19pre10aa2 with added ext3 0.9.18 and will report if something strange will happen. I might also write some observations to lkml ... redhat's kernel with rmap prooved to be way inferior to -aa kernel on this busy mail server ... Btw, this is a redhat 6.2 system with most of the updates, gcc reports version version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release). -- Jure Pecar
