I see the same problem on an AOpen 1557GLS laptop with a mobility chip set. Skype triggers this bug in a few minutes. 01:00.0 VGA compatible controller: ATI Technologies Inc RV350 [Mobility Radeon 9600 M10] (In reply to comment #1) > I see the same problem on an AOpen 1557GLS laptop with a mobility chip set. > Skype triggers this bug in a few minutes. > > 01:00.0 VGA compatible controller: ATI Technologies Inc RV350 [Mobility Radeon > 9600 M10] It looks like the bug is still present with DynamicClocks disabled, it is just much harder to trigger (every other day, instead of minutes). Sorry! I do have an IBM R51 with Radeon 7500 mobility card and do have the same problem. Around 80% starups of x.org will crash my Linux completely. Interestingwise the percentage of startup crashes drops drastically, if I do a lot of keyboard input and mouse movement during start. In that case I manage about 80% of startups to be successfull. If I turn off the Dynamic Clocks feature, the systems seems to start every time without any problem (but in that configuration the fan of my Thinkpad didn't stop anymore). Volker Workaround: use this little tool to underclock (and overclock) your radeon 7500 M http://forums.gentoo.org/viewtopic-t-343029.html But no dynamic clock switching. Tested it for 2 hours, no problems except on extreme underclocks. T42 2374-zep is also infected. Run for several weeks with no problems... suddenly hangs on every boot with dynamicclocks enabled. Anyone working on a solution? Anyone contacted IBM and/or ATI for help/specifications? IBM seems to have helped out on those thinkpad problems before, hopefully they will still after being Lenovo!! Does fixes in bug 3621 https://bugs.freedesktop.org/show_bug.cgi?id=3621 solve this? Anybody thried? I committed a small fix up of some errors in the dynamicclocks code. The changes are in xorg cvs. It may help with this bug. (In reply to comment #6) > I committed a small fix up of some errors in the dynamicclocks code. The > changes are in xorg cvs. It may help with this bug. Have been running the new code for a couple of days, no hangs. BUT!!! It seems to have no effect on the powerconsumption anymore!? My Radeon 7500 on my Thinkpad T42 gets equaly hot with and without dynamicclocks on ! Any ideas?

If not it's possible the BIOS already enables dynamicclocks, in which case, enabling it in the driver will make no difference. *** Bug 2790 has been marked as a duplicate of this bug. *** (In reply to comment #8) > Did it used to make a difference when it was enabled?

But if boot into Windows XP, the GPU slows down as expected, and the fan stops running, Xorg driver keeps the GPU hot and the fan keeps running... this is bad for a laptop. Do we have the specs to enable what ATI calls PowerPlay ? And may I see them? (In reply to comment #10) > (In reply to comment #8) > > Did it used to make a difference when it was enabled?

And may I see them? No, ATI has not released the specs to powerplay. Just to be clear the DynamicClocks code is not powerplay; all it does is set the various GPU clocks to dynamic mode so they scale based on load. Powerplay involves a lot more. MT: Is this fixed in the latest code? *** This bug has been marked as a duplicate of 1912 *** not a dup of 1912 Ping to the bug poster! Closing this bug due to the lack of activity from the bug submitter. If the problem still exists in a _current_ version of xorg, please reopen. |
