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.
