In theory, the fix should be upstream here:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=126c098296c8f96cf7f6ca0fdb47265ac7994f00

(not in a released -rc yet, but should be in -rc7).

Following Peter's idea of relaxing writeback throttling, Lin Ming
and I tried the idea of totally disabling writeback throttling by
doing benchmarks with the following parameters:

echo 60 > /proc/sys/vm/dirty_ratio
echo 50 > /proc/sys/vm/dirty_background_ratio

The result is encouraging: the iozone performance is restored to the
level of 2.6.29-rc5!

We'll continue to evaluate the dirty/throttling numbers with Nick's patch.

Thanks,
Fengguang

No!

This is not about parallelism, this is about making sure there is a
limited number of dirty pages, that means the tasks generating dirty
pages will _have_ to wait. You simply cannot delegate that.

Furthermore, the task throttling explicitly wants to throttle the task
that generates all those dirty pages more than other tasks. So pushing
the throttle out to pdflush will destroy the whole scheme.

The reason we want to make the heavy dirtier throttle sooner is that
other tasks, who only occasionally dirty a page, don't get caught in the
massive throttle latency.

Yup - just tested -rc7 and the problem is gone. Thanks!

Well, well... nobody really cares about this bug, so it's still
there. Seems this automatic reminder will be persistent until 2.6.30.

This looks to have been a case of old-userspace..upgrading to
xorg-intel-video 2.6.1 (ubuntu Jaunty Alpha5) fixes STR here.

Well, thanks, but I'm not really sure if this is a good news.

Jesse, Eric, does it mean we now break resume on anything earlier than 2.6.1
on the Harvey's hardware?

There's not much information (dmesg, Xorg.0.log) with this bug -- I'm
guessing he's using KMS, given that that commit was where the problems
started. If so, yes, you really do need good userland for KMS to work.

Yep, turns out I had KMS turned on in my config...I thought I'd disabled
it, sorry for the noise.

BTW, Is suspend generally supposed to work with KMS and the 2.6.1 (or later) X

I pulled a giant pile of KMS bugfixes into 2.6.2, so I'm not sure about
2.6.1.

We've still got some work to do with making our suspend/resume path
really complete for KMS. We're missing some register setup that UMS
does, so behavior can be a bit random. The current plan is to switch to
using the KMS modeset paths for resume, so we hopefully have reliable
(or at least consistent) mode setting behavior, and then fill those
remaining register writes in around it. Basically, a separate
suspend/resume path for KMS, when we have full control of the device.

It is a DRI bug, assigned to
