I regularly (once or twice a week) test 100 corrupted images of vfat, udf, msdos, swap, iso9660, ext2, ext3, ext4, minix, bfs, befs, hfs, hfs+, qnx4, affs and cramfs on each of my two test machines.
They are all pretty stable, one remaining thing on my list i didnt have time to look into was an issue with fat (msdos) triggering a bug in buffer.c the other is a warning with ext4 in jbd2/checkpoint.c:166
If there is a filesystem you are interested in thats not on the list or that you want me to test a bit more, just let me know
Greetings, Eric
