Subject: | Ext4 detection fails if test_fs is not set |

The problem is, that in 2.6.28 ext4 no more has the test_fs flag set (tune2fs -E test_fs ... ), without which the recognition of the fs type fails. Adding the flag again makes it work. And e2fsck automatically clears the test_fs flag when the fs is checked with the new kernels. The rootfs was converted from ext3 by just doing
tune2fs -O extents /dev/... The version of grub is from debian experimental, dated 2008-11-20.I guess that for now, as a workaround I can use the rootfstype=ext4 boot parameter...
