With this commit my PC freezes sometimes when get on/off standby: $> xset dpms force standby I have always had these problems, please refer to: https://bugzilla.kernel.org/show_bug.cgi?id=spina but they are occurred rarely, recently. With your commin on 17/06/2011 (commit 122b471f734aa07427b01d4bec35ff1ac28290b5) the problem seemed to be solved. However, with the commit in object it always happens. I can see a blinking screen but I have to halt the PC with magic key. Best regards, Emanuele
Hi, I have tried some commit in reverse mode. - Jun 17: same problem. - Jun 16: same problem, but less often. - Jun 13: so far so good. Emanuele
Please attach your xorg log and dmesg output.
Created attachment 48905 [details] Xorg.log
Created attachment 48906 [details] dmesg on boot As I have already said in the other bugzilla, when my I do: xset dpms force standby or echo "low" > /sys/class/drm/card0/device/power_profile the first time I have this message: --- NMI: PCI system error (SERR) for reason a1 on CPU 0. Dazed and confused, but trying to continue --- but, if I follow you suggestion this disappears: --- You can disable the PCIE lane changes by removing the call to radeon_set_pcie_lanes() in rs600_pm_misc() in rs600.c. ---
Hi Alex, I saw your last commit one minute ago. Have you discovered what happens on my PC, yet? Do you need more infos? Best regards, Emanuele
Have you changed the kernel you are using or just the ddx? With KMS, there ddx doesn't really do much with respect to modesetting. It just calls into the kernel.
Alex, I'm using the latest vanilla stable kernel (2.6.39.3). Sorry but, what is the ddx? Emanuele

Thanks for your reply. So, is there a bug in the Kernel? I use to compile the kernel by myself, did I forget something? But, how is possible that with different commit of ddx there are different situations? Thanks a lot, Emanuele
It's hard to say. That's why I was trying to figure out which components you changed (just ddx, ddx and kernel, ddx, kernel, and mesa. etc.) as they could all be to blame potentially. It might be a 3D screen saver that kicks in and hangs the card due to a bug in the 3D driver.
I have never used screen saver. My Server X is configured in this way: xset s 300 xset s blank When I want to force the standby I use: xset dpms force standby I can do all the tests you want, Emanuele
Hi Alex, now I'm using kernel v3.0.4. I noticed that I have freeze also when I put my current wire into socket, sometimes. Remember that I receive this message on standby or when I do: --- echo "low" > /sys/class/drm/card0/device/power_profile --- NMI: PCI system error (SERR) for reason b1 on CPU 0. Dazed and confused, but trying to continue --- and I do this when the current wire is pulled off whereas I do: --- echo "auto" > /sys/class/drm/card0/device/power_profile --- when is inserted. I have noticed also that sometimes I receive that message at boot time: ---[drm] Initialized drm 1.1.0 20060810 [drm] radeon defaulting to kernel modesetting.

Did removing that call only cause the NMI message to disappear, or also the freezes? Is it still the case with a current kernel?
BTW, please refer to Git commits by their commit IDs rather than by date.
Hi Michel, (In reply to comment #13) > (In reply to comment #4) > > but, if I follow you suggestion this disappears: > > --- > > You can disable the PCIE lane changes by removing the > > call to radeon_set_pcie_lanes() in rs600_pm_misc() in rs600.c. > > Did removing that call only cause the NMI message to disappear, or also the > freezes? we'll see. I disabled that call and the NMI message has been desappeared. I also tryed 'xset dpms force standby' some times and so far so good. > Is it still the case with a current kernel? --- $> uname -r 3.0.4 --- With 3.0.X kernel freezes are different. Now I can move the mouse or I can use keyboard, sometimes. In these cases, I'm not obliged to shutdown PC but I can reboot it: I have to press the halt button on my case and I can force reboot with CTRl+ALT+DEL after some seconds (I think when X server is killed, but I can't see nothing). Thank for all and best regards, Emanuele
(In reply to comment #13) > Did removing that call only cause the NMI message to disappear, or also the > freezes? Is it still the case with a current kernel? Michel, after a week we can say: "yes, also freezes have been desappear". Now, all is good!!! But, when I update the kernel with new increments, patch obvously fails for this file. Emanuele
