None of this has anything to do with KDE or its apps, except that they're
simply other apps on the system not able to use the filesystem, because
the filesystem cannot be properly mounted.
The problem is thus not with kde, but with your system apps. You
mentioned that you were using kernel 2.6.32.x, which I can confirm works
well with ext4. What versions of util-linux and e2fsprogs do you have?
These contain the mount command and the various ext utilities.
Perhaps you're running outdated versions there. FWIW, here's what I'm
running on ~arch (~amd64 and ~x86, ~ indicates unstable version) gentoo,
With those and kernel 2.6.32.x, I have absolutely no trouble mounting ext4
fileystems as ext4, as set in fstab. I know this as while I run reiserfs
on my main disks on both my workstation and netbook, I'm running ext4. set
to use no journal, on the thumbdrive I'm using to shuffle files back and
forth using local rsync, until such time as I get the network properly
setup to do it directly, without use of the thumbdrive as intermediary.
Thus, that thumbdrive and the no-journal ext4 filesystems it contains, is
getting a bit of a workout ATM, being mounted first on one system then the
other, then rsynced as appropriate. Believe me, if either the 32-bit
native netbook or the 64-bit native workstation were incapable of mounting
ext4 from fstab, I'd know it well by now!
