text/plain Kernel update bring those freezes to my mine install what have no kde 4.12 installed so i think that problem it's in kernel no in kde. dmesg shows these error lines when it's freezing. [drm] stuck on render ring ing_stuck] *ERROR* Kicking stuck semaphore on render ring This seems to be some graphics/kernel issue show i will change this against kernel from kde.

(none) This is a problem with sna vs uxa acceleration. edit /etc/X11/xorg.conf and add Option "AccelMethod" "uxa" so it should look something like: Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "uxa" EndSection It fixes it but now there is lot of tearing because tearfree needs sna. If you are using: Option "AccelMethod" "sna" Option "TearFree" "true" Then try to add to kernel command line: i915.semaphores=1 Mageia have by default i915.semaphores=1 so it won't change anything. for i in /sys/module/i915/parameters/*; do echo $i=$(cat $i); done /sys/module/i915/parameters/semaphores=-1

14301 No, it has "-1" wich means "chip default setting" try to force it with i915.semaphores=1 It's working i understand wrong that -1 means it's disabled as default. Needed to edit grub2 efi to do it,first try to do it like arch wiki says creating this conf file /etc/modprobe.d/i915.conf with options i915.semaphores=1 but i won't work even i used dracut to rebuid initrd. I get again those freezes it seems it was fixing that problem but now those are back. Did it work with an earlier kernel, and if so wich one ? Yes it worked with 3.12 kernels without setting i915.semaphores=1 problem only exist in 3.14 kernels. If i set i915.semaphores=0 freezes are gone so it's so weird bug. I found bug report from kernel bugzilla can be releted or not. https://bugzilla.kernel.org/show_bug.cgi?id=77691 I get it working with i915.semaphores=1 noticed it was in grub2 but it was still -1 needed to edit /etc/grub/default and update-grub now it works fine without any freezes. I close this bug because have working solution i reopen it if this problem come back,Mageia 5 have no this bug so it will be fixed already. Status:
