It seems that the bug has been found. https://lkml.org/lkml/2012/10/28/1

Kernel versions 3.4, 3.5, 3.6 have the bug. Kernels 3.2 and 3.3 are ok. Slackware-14.0 uses kernel 3.2.29 which is fine.

(Note that the bug was not added in any stable kernel iterations 3.4.x or 3.6.x. It was already in the original 3.4.)

From another of Eric's posts in the thread linked to by Petri:
Quote:
So anyway, turning on journal_async_commit (notionally unsafe) enables journal_checksum (apparently broken).
So, turning on a potentially unsafe option, turns out to be actually unsafe, because it is broken!
I'll mark this as SOLVED. Anyone using sensible mount-options won't be hitting this.

Be careful.

ReiserFS used to be good, but in recent kernels it has both momentary data corruption and performance problems. http://www.linuxquestions.org/questi...xt4-4175425294

These problems went away when I switched to ext4. Since not many people use or care about ReiserFS, its quality has gone down hill.

I liked RieserFS. It was fast. Or so it seemed. Somewhere along the way though I switched to ext4 for reasons I can't even remember.

ReiserFS is working fine on this system I have now (ASUS M5A97LE R2.0, AMD Athlon II X2 260, 4GB RAM) and on my old system (ASRock A770DE+, AMD Athlon II X2 250, 2GB RAM which I gave to my 73 year old mom as *her* old system was a P-3!). I've yet, in all these years of reiserFS use exclusively had a problem with it. I'll keep using it until the day it *does* start to screw up, but in thirteen years this month (so far) it hasn't and it is nice and stable and takes the beatings of power outages and brown-outs extremely well, imho.

I never had any issues with it either.

I've used it on External Drives quite a bit. Never lost data.

Even on crap hardware with dying controllers, it recovered.

I'd use it before I'd ever go back to NTFS.
