[Ocfs2-devel] crash while creating a lot of files - jbd2 assertion failure

[Goldwyn Rodrigues]

Hi,

ocfs2 crashes most of the times when I try to create a lot of files on
the filesystem. The details are:

Arch: i686 (2 processors)
Kernel version: 2.6.35.3
Script to reproduce:
for i in `seq 1 1048576`; do echo $i > f.$i; done
Reproducible: most of the times
fs-features: indexed-dirs,local,noxattr

dmesg:
