If this works in Redhat and SUSE, isn't it trivial to just take use the same
kernel patches as they do?
(I know nothing about it, so I assume that it isn't trivial. It was just a
thought)
Does anyone know if this works in Debian?

Hi Christian,
I know, maybe you have already spent a little time with issues like
this, but could you try it again with a custom built 2.6.25-rc8 kernel?
(Don't use an earlyer 2.6.25-rc version than -rc8; there were some bugs
in the dm-specific code before)
There were a lot of changes concernin

I have upgraded to the Hardy beta, and I am running with a
2.6.24-12-generic kernel currently.
The problem is _not_ fixed. I have dm-crypt with LUKS and ext3, and the
problem is very easily felt. The whole system is very slow when doing
anything on the disk. This is in total contrast to how the sy
according to the upstream bug tracker, this bug has been fixed in
2.6.24. Can someone who is affected by this bug confirm that it has been
fixed by upgrading to hardy?

It's just that I no longer have the "hard" hangs I had before, since I
upgraded to the fast dual-core-CPU.
I'm just a user, so I don't know if is because of the new CPU exactly,
but it was a real issue for me then.

Sounds great. But when can I expect this to be fixed in Ubuntu? Will the
next release of Ubuntu use this kernel? Or will this fix be imported
into Ubuntu, so that I can expect a kernel u
Hi,
I already reported it on the Linux kernel Bugzilla.
Have you tried the latest release-version of the Linux kernel?
Please try it and compile 2.6.24-rc4 if you can. This bug is supposed to
be fixed with that kernel version.
Sadly, I own a dual-core-CPU now, and this makes a bit hard for me

Canonical will do anything with this bug. Probably better putting it on

Maybe this bug should be renamed from "Write load on DM-Crypt LUKS
partition with reiserfs jams system" to "Write load on DM-Crypt LUKS

nothing to do with reiserfs.

I can confirm this on current gutsy. This is very annoying, makes using
encrypted partitions nearly impossible (core2duo and 500GB sata disk).
With the dual-core processor the computer actually performs fine, the
wait-time reported by top is 50% as only one core is being hogged, but

Someone suggested to renice the kjournald process as a workaround.
Is that really safe?

I use LUKS with ext3 on Kubuntu Feisty.
When I have moderate disk activity the system is almost unusable.
I think this is a scheduling problem.

This issue seems to be that you are doing it on an encrypted filesystem.
The kernel obviously has to perform a lot of IO intermixed with
computational overhead to do this.
I don't know if the performance problem is expected or not. It all
depends on what encryption method you are using, etc.
