Subject: OOPS BUG at fs/ext4/inode.c:1853

Hi,

Here is a kernel oops using the latest fedora 12 kernel.  Machine is a Intel(R) Xeon(R) CPU E5430  @ 2.66GHz, running in 32bit mode, normal SATA disks.  Filesystem was created in fedora 10, and machine upgraded via yum to Fedora 12.  Is reproducible using "stress-1.0.2" from http://weather.ou.edu/~apw/projects/stress/

Command line to reproduce was:  ./stress --cpu 4 --io 1 --vm 1 --vm-bytes 128M --hdd 1  

Please cc any reply to me, and all help is appreciated.

Cheers,

Rusty
