Description Nils Philippsen 2011-02-24 12:05:46 UTC
Description of problem:

During the F15 Radeon testday -- https://fedoraproject.org/wiki/Test_Day:2011-02-23_Radeon -- two of my machines encountered some hard lockups where the screen went dark, they weren't reachable and didn't react to any other "stimulation" from outside.

Version-Release number of selected component (if applicable):
kernel-2.6.38-0.rc5.git5.1.fc15.x86_64

and whatever else was put on the live ISO: http://adamwill.fedorapeople.org/gfx_test_week_201102/gfx_test_week_20110221_x86-64.iso

How reproducible:
Somewhat.

Steps to Reproduce:
1. Conduct tests as described in the wiki, eventually running glxgears and a video concurrently helps(?)
  
Actual results:
Suddenly everything is dark (screen _and_ previously lit kbd LEDs), no reaction on any key presses, machines don't ping from outside.

Expected results:
No crash.

Additional info:
Smolt profile for the machines:

RS780M: http://www.smolts.org/client/show/pub_422b3246-f396-4785-8231-26ef5fe5fdb2
RV620: http://www.smolts.org/client/show/pub_3e3f5e3d-ad22-4d0f-aa79-b2e88e522c6c

For further tests with the RS780M machine I'd probably need another live image as it is on F-14 and doesn't have enough space to install another OS beside.

Comment 1 Nils Philippsen 2011-02-24 12:08:11 UTC
FWIW, on the RS780M machine I saw a "melting screen" (faded to white) one or two times, graphics and kbd were hosed but it was pingable afterwards. I don't know if this is related.

Comment 2 Dagan McGregor 2011-03-03 05:24:50 UTC
I also have issues with the radeon driver on my two ATI cards, and it is related to bugs in the kernel-2.6.38-0.rc5.git5.1.fc15 release.

The kernel -rc4 and -rc6 (fc16) both work fine.

This is an issue with the F15 Alpha RC2 LiveCD also.

Request radeon fixes from 2.6.38-rc6 kernel are patched to F15, or the F15 release is moved to 2.6.38-rc6 kernel.

I have an ATI 5650 mobile video card in Acer laptop, and ATI 4870 PCI-E card in my desktop, both fail to load in anything other than Basic Video mode with F15 Alpha.

Comment 3 Chuck Ebbert 2011-03-04 02:36:58 UTC
2.6.38-rc6-git6 is already submitted:
https://admin.fedoraproject.org/updates/kernel-2.6.38-0.rc6.git6.1.fc15

It has been in updates-testing for a while, and -rc6-git4 was there earlier; is that repo not enabled on your machines?

Comment 4 Dagan McGregor 2011-03-04 03:54:55 UTC
 Is that package for updates-testing only available through F15 Alpha installs?

 I see the fedora-release-rawhide package has jumped up to F16, and I can't work out any way to keep getting F15 packages onto my current F14 install?

 Am I missing a .repo file somewhere?

Comment 5 Josh Boyer 2011-10-11 17:53:49 UTC
F15 has moved well beyond 2.6.38-rc6 at this point.  I'm going to close this bug out.  If you are still seeing these issues on the latest F15 or F16 kernel, please reopen.
