File system has incompatible feature enabled....

Compatible features are has_journal, dir_index, filetype, sparse_super and
large_file. Use tune2fs or debugfs to remove features.

I don't see in the mkfs.ext3 man page why any existing features should be
incompatible. Where's the list of what's compatible? Why doesn't the
installer say which feature is incompatible? Why doesn't it say which
filesystem has the incompatible feature?

I suppose this happens because I preformat prior to installation:

mkfs.ext3 -b1024 -I128 -J size=400 -Lkubuntu -m1 /dev/sda12

tune2fs lists these existing features: has_journal ext_attr resize_inode
dir_index filetype sparse_super. Size is 3582463 blocks.

Last several attempts to install Jaunty & Karmic (from netboot mini) results
in this stoppage. What's the best procedure to solve it, other than maybe not
formatting in advance? I tried:

# tune2fs -O ^ext_attr /dev/sda12
tune2fs 1.41.9 (22-Aut-2009)
Clearing filesystem feature 'ext_attr' not supported.

after which e2fsck, but it didn't help. tune2fs -l afterward still reports
ext_attr enabled.

I tried mkfs.ext3 -b1024 -I128 -J size=400 -Lkubuntu -m1 /dev/sda12 from
tty2, but the same set of features results, including the ext_attr which is
not in the supported features list.

I finally got around this by setting no partitions for mounting except sda6
swap and sda12 /. Those I unset were sda15 for /home, sda5 for
/disks/hda/boot and sdb6 as swap.
