Hello,
I upgrade to each new kernel release and with 3.5.1 (from 3.4) I can no
longer mount my 60TB ext4 volume.
If I boot back to 3.4, it works fine.
Details here:
https://lkml.org/lkml/2012/8/10/205
Anything I can do besides testing each 3.5-rcX to find where the regression
lies?
Justin.

I'm not at all familiar with ext4 internals, but as always, an wasy way
is to bisect such a problem. Any change you can do that?

Hi,
Thanks, will save this for the future-- would of done this but Eric
Sandeen found the offending patch, I reverted it and I can mount the
filesystem now.
The bad commit was 8aeb00ff85ad25453765dd339b408c0087db1527 (per sandeen)
Justin.
