radeon drm locking problem: xorg freezes with gutsy and radeon 7500

[Georg Sauthoff]

Binary package hint: xorg

I upgraded from Ubuntu Feisty to Gutsy. In Feisty I hadn't any problems related to X. I easily ran the Laptop for 30 days with suspend/resume.

I am using a Thinkpad R40 with Radeon 7500.

From time to time X freezes, i.e. no mouse cursor, nothing moves. Doing a SysReq + S works. In the kern.log I see after a reboot:
Mar 1 11:04:42 tp kernel: [95316.248000] sd 3:0:0:0: Attached scsi generic sg1
type 0
Mar 1 11:48:46 tp kernel: [97960.032000] [drm:drm_lock_take] *ERROR* 1 holds he

Mar 1 11:53:37 tp kernel: [98251.160000] Emergency Sync complete

My Device Section from xorg.conf looks like:
Section "Device"
 Identifier "card0"
 Driver "radeon"
 VendorName "ATI Technologies Inc"
 Option "DynamicClocks" "on"
 Option "monitor-VGA-0" "mon-vga"
 Option "monitor-LVDS" "mon-lvds"
EndSection

Best regards

drm is in the kernel. You should try running a Hardy livecd for awhile

ups, i mis-clicked this 'also needs fixing there ...' button ...

Closing -ati component since it seems to be a kernel issue.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

Ive just installed the mythbuntu intrepid version on an R40E. After boot the screen displays the logon panel but the keyboard and mouse are dead. I did a build of the latest kernel linux - 2.6.27-7.10 but still the same problem. I can get to terminal screen.

Ive just installed 8.10 Desktop and there is no problem. Must be a problem with the mythubuntu cd.

gsauthof, since you are the original bug repoter, is this still an issue for you with the Intrepid Ibex 8.10 release? Thanks.

[Georg Sauthoff (g-sauthoff)]

Leann, no it isn't an issue for me with later versions of ubuntu.
