>Description:
Kernel compiled with WAPBL option corrupts ext2 file systems.
Maybe some incorrectly handled hook in UFS layer?
>How-To-Repeat:
Perform some work on ext2 file system, eg. compile.
Check the file-system consistency (or even file contents).
>Fix:
Workaround: compile kernel without WAPBL option.
