--- Comment #5 from Jesse Brandeburg <[email protected]> 2010-05-25 17:56:58 --- I was unable to continue using ext4 for development since it was not reliable through panic. Was there ever any progress on this issue? Due to this bug I have been telling everyone I work with to not use ext4.
It is a pretty easy bug to reproduce, isn't there something we can do about it?

--- Comment #6 from Eric Sandeen <[email protected]> 2010-05-25 18:02:53 --- Jesse, are you still running with data=writeback (as comment nr. 1 seemed to indicate, since you said you would -try- data=ordered...) - data=writeback is just not safe at all for anybody, anywhere, any time, unless you plan to recreate all data post-crash.
With default mount options (which includes data=ordered) do you still see this problem on upstream kernels?
In the end, though, you have to realize that buffered data which is not synced to disk -will- be lost on a crash. This is true for all filesystems, though the window of "opportunity" may differ....
