SubjectRe: 2.4.23pre4 VM breaks in LTP


Andrea, do you have any idea of what could cause this? A missing merge may
be the cause, as Andi pointed out. I wont have time to look further into
it during the weekend and next week (Europe conferences).

Andi, about the ext3 BUG I'm waiting for Stephen. I remember he knew how
to fix the issue but didnt had the patch ready yet sometime ago.
