You are right. I'm using e2compression latest patch (for 2.1.130
I think it was 0.4.16). Howevere home was not compressed :((
(when it started reporting file system contains errors check forced
on every boot I have decided to do mke2fs on it again). I have
closley examined my syslog file and also posted what was problem
that might caused mess (either was problem with ide cable or for some
other reason disk did LBA/CSH translation). I also don't get why
does e2compression causes problems that e2fsck can't repair :((

That is true. e2fsck -b8193 couldn't restore anything :~~~((((

Fortunately this machine has only 100 users, only my friends, and it
is running development kernel... On machine with 2000 or more users I
certanly wouldn't run 2.1.xx kernels :)
