In the morning I turned on home computer and during KDE startup I got many error requesters such like “unable to write file umbaumba” which was bad. After quick look I found that ~/.kde/share/apps/ directory was changed to something strange…
Quick "init 1" and started "reiserfsck --fix-fixable /dev/hda6" (after umounting of course). If found 2 fatal errors…
I get this partition working but now it’s time to get rid of reiserfs — I’ll move to XFS.
