Hi Milan,

I'm aware of your new v5 patch (which should include several
improvements (or potential fixes in my case) over the v3 patch)

as I already wrote my schedule unfortunately currently doesn't allow
me to test it

* in the case of no corruption it would be nice to have 2.6.37-rc* running :)

* in the case of data corruption that would mean restoring my system -
since it's my production box and right now I don't have a fallback at
reach
at earliest I could give it a shot at the beginning of December. Then
I could also test reiserfs and ext4 as a system partition to rule out
that it's
a ext4-specific thing (currently I'm running reiserfs on my system-partition).

Thanks !

Matt
