But I do, I kept my bad partition all the times, (it was just
/usr/ports/distfiles - lucky me).

With normal, stock RELENG_6 sources from yesterday:

Kernel with UFS_EXTATTR and UFS_EXTATTR_AUTOSTART -> panic on mount
Kernel with UFS_EXTATTR without UFS_EXTATTR_AUTOSTART -> works

I recently upgraded my RAM, so I had too little swap to dump, but if
a dump needs to be generated, I'll remove a few of them and we'll
have one.
