Summary: System freeze upon X startup with KMS enabled (RV730)
Product: DRI
Version: XOrg 6.7.0
Platform: Other
OS/Version: All
Status: NEW
Severity: major
Priority: medium
Component: DRM/Radeon
AssignedTo: dri-devel@lists.freedesktop.org
ReportedBy: info@noctus.net

kern.log messages upon freeze
Trying to start X with KMS enabled on my HD4670 (RV730) card freezes the system
and I have to SysRq out of that situation. Since this only happens with the
final release of the 2.6.35 kernel I am currently stuck with the RC6 which does
not display this behavior. See the attached kern.log output in case of such
freeze.
I am running the latest Git masters of both xf86-video-ati
(5a7c9d94733a0db1d3565447acc9f0e751db5950 here ATM) as well as mesa
(f3ec111b0af9d268e6b3c6d3226a448d19e45d8c here ATM).

Sorry but I cannot verify the patch ATM since that seems to require a recent
(but at least 2.6.36) kernel whereas I can only build 2.6.35 here. I’ll leave a
comment as soon as a newer version is packaged.

It should apply to 2.6.35 as well.

Not really. The first part of the patch looks like this:
> diff --git a/drivers/gpu/drm/radeon/r600.c b/drivers/gpu/drm/radeon/r600.c
> index 667c237..5668b90 100644

That function looks like this here though:
> void r600_ioctl_wait_idle(struct radeon_device *rdev, struct radeon_bo *bo)
> {
> WREG32(R_005480_HDP_MEM_COHERENCY_FLUSH_CNTL, 0x1);
> }
Thus this hunk already fails to apply.

Mathias, in your case it seem to be something else as the problematic patch
(812d046915f48236657f02c06d7dc47140e9ceda) was not applied until after 2.6.35.
Any chance you could bisect?

I am not really sure what you are asking me to do. Shall I apply the patch from
812d046915f48236657f02c06d7dc47140e9ceda here as well and the patch from this
report after that? Otherwise I guess I can also wait for a kernel 2.6.36 RC to
hit my package repositories.

… is what I did now and I can start just fine. So this issue also seems fixed
for me.
