Hello, 

Sorry if this message misses the thread.

Could this be connected ?
http://marc.info/?l=linux-ext4&m=123755620515122&w=2
Ext3/ext4 corruption on block ramdisk. Also HTREE is corrupted under stress
tests with several concurrent fsstress (LTP util) processes.

Tested on latest 2.6.29-rc8 kernels, on quad Xeon machine with enough RAM.
Testcase: http://marc.info/?l=linux-kernel&m=122666866015665&w=2
