There Might Be Another EXT4 Corruption Bug
It was only days ago that an EXT4 file-system corruption bug affected the stable Linux kernel, which was finally patched yesterday. Now though it looks like there may be another EXT4 corruption bug affecting the stable kernel.
A Phoronix reader, Ernest Boyd, sent in an email "Unfortunately another problem appears to exist which more simply produces Ext4 shutdown corruption." From his LaunchPad bug report, it's easy to reproduce this problem:
1. Format and label a target Ext4 partion using Ubuntu 12.04The bug is marked as critical since it results in file-system corruption and is reproducible with the user having made an image of the Ubuntu 12.10 64-bit installation to reproduce. "I can recreate the symptoms of Ext4 filesystem corruption 100% of the time by restoring from the image, booting, logging on and shutting down."
As of yet there's no comment by the upstream Linux kernel developers or the Ubuntu kernel folks.
