Subject: frequent kernel bugs with 2.6.26-gentoo-r1

(i sent a part of this mail from another email address which is not registered in this list, so i'm not sure whether it was deliverd or not. so here it is again with some more information)

hi all,

i used ext4 some months ago but switched back to ext3 then.

today i wanted to try out ext4 again and did the following:

i'm using latest gentoo-kernel, which is based on 2.6.26.2 and some few
patches
(patchlist: http://dev.gentoo.org/~dsd/genpatches/patches-2.6.26-1.htm).

i patched the kernel with
ftp://ftp.kernel.org/pub/linux/kernel/people/tytso/ext4-patches/LATEST-2.6.26/2.6.26-ext4-6.bz2
and compiled it successfully.

after a "ssv flags 4" and a "tune2fs -O extents" i could mount one of my
ext3 partitions as a ext4dev-drive. first, everything seemed to work,
but after some read/write to that drive i got the first kernel oops.

thought it might be because it was an old ext3-drive, so i formated the
drive with mkfs.ext4dev. but no change, still the same problems. now i'm
nearly always getting a kernel bug on umounting an ext4-drive (and then
the device is not accessible/mountable anymore). here's the recent one:

and here's a kernel fault while using the filesystem (happened on quitting firefox, the profile is located on the drive). the drive was unusuable after this:
