Please attach full kernel log with 2.6.34, if you can't boot because of KMS
boot with: radeon.modeset=0 3
Then log as root and do (through ssh would be easier):
rmmod radeon
modprobe radeon modeset=1
Then save the kernel log (/var/log/messages usually) and attach it here

Which kernel do you mean the working 2.6.34 or the non working 2.6.35-rc1 ?

/Var/log/messages from non-working kernel (2.6.35-rc1)

I think the error is unrelated to the problem, as airlieds drm-radeno-next tree
doesnt show the bug in native_sched_clock but booting with modeset also does
not work. I will also attach messages from airlieds 2.6.34-tree.

Is it just LVDS?  Does an external monitor work?

New code does not work when plugging in an flatscreen per dvi. Still boot hangs
with dotted white vertical lines on lvds, whereas dvi says no cable connected.

However i noticed a new problem when plugging in dvi with 2.6.34. When i plug
dvi at running time it works as espected (aka dynamically configures monitor),
however when i plug dvi in at boot time the lvds becomes all white as soon X
starts and only dvi works. I will open a new bugreport for this.

Please boot with drm.debug=15 and attach kernel log. Also please boot with no
external monitor connected. So we can fix bug one at a time. (need log with a
working and non working kernel)

I bisected to the same commit on my HP Compaq nx6325 laptop with integrated
RS482. 2.6.34 was fine, 2.6.35-rc1 freezes. This is with only the LCDS, no
external monitor. I'll attach logs when I get back home, if still needed.

Does reverting ce8a3eb20c4cb7d9e0c33e7560070688cd9066fc actually fix the
problem?  Booting with drm.debug=15 should work as well since that would
re-enable the debug code that commit turned off.

dmesg with drm.debug=15 from working kernel

Attached is log from working kernel. I am currently unable to get log from not
working kernel, as soon as i modprobe radeon with modeset the system hangs,
magic-sysrq does not work.

Booting with drm.debug=15 does not prevent the hang, i try to revert the commit
an report back.

Reverting the commit against 2.6.35-rc1 and booting with drm.debug=15 worked
(eg no crash, but white screen, which could be solved by vbetool dpms off /
on), however after i rebooted and removed the drm.debug option it crashed
again. Also all later tries (with and without drm.debug) crashed.
A timing problem ?

Does applying the following two patches help?
http://people.freedesktop.org/~agd5f/0001-drm-radeon-kms-add-support-for-internal-thermal-sens.patch
http://people.freedesktop.org/~agd5f/0001-drm-radeon-kms-pm-Misc-fixes.patch
The first one isn't relevant to your hw, but the second one won't apply cleanly
without it.

Oh damn, ignore my previous comment #11, as it looks like I was way to fast
looking at the commit ID. For my freeze the actuall one is
ce8f53709bf440100cb9d31b1303291551cf517f which is probably another bug, which I
will report separately. Sorry for all the noise.

The patches in comment #15 are relevant for that commit, although you'd
probably want to open a new bug anyway.

The patches work, system no longer crashes. Thank you. However now i get an all
white-screen as soon as kms gets activated (same white screen as described in
comment #9), i can work around it with an vbetool dpms off / on cycle. Should i
open a new bugreport for this, and if so which logs do you need for the new
problem ?

Thank you for your time.

Although startup now works i get screenflickering when runing, also the system
sometimes hangs when using 3D applications (compiz, kwin-compositing,
openarena, padman), this worked without problems with the old pm-code.

Thank you
