Hi! I have a severe problem - I was a fool and made / (root) ext4 (at least not /home, thank god) and somehow some corruption occured. While running fsck, it keeps segfaulting, complaining about fast memory corruption (segfaults always at the same inode, always when I tell it to fix it). I *think* the issue was addressed in e2fsprogs-1.40.2 (from what I understood in the changelog) - but I can't find a patchset for it... I tried to do the 1.39 patch on the 1.40.2 source but there were more then a few mismatches and it didn't build. with enough work, I might be able to build it, but I strongly prefer a ready patch/tarball which I know will work and I haven't found any on the net. Can anyone please point me to one or send one to me, or advise on a different solution? Thanks in advance, Kosta. -- Kosta.tk
