Hi all, I'm an end user and I'm having problems which I believe are ultimately caused by an issue with the Intel kernel driver. When I am running programs that use a lot of images (e.g. GIMP, Firefox with YouTube and Google Maps) then after a short while my whole machine will grind to a halt, to the point where even my audio buffers don't get updated so I hear the same 500ms of audio repeated in a loop until the system comes back to life again. Typically the system will stop responding from anywhere between 30 seconds to a minute, and usually it returns to service after the kernel OOM killer has ended a process - typically Firefox as it uses the most system memory. Of course it's not a system OOM problem, because the system has 16GB of RAM and the problem still happens even if less than 4GB is in use. Looking at dmesg, the problem always starts with a message like this: Purging GPU memory, 69632 bytes freed, 48553984 bytes still pinned. Since system memory is fine, I can only assume this means that there is some limit on the amount of memory the video driver can access, and it has reached that limit. Here is the top of the backtrace, if it's relevant: Call Trace: [<ffffffff812c0dc9>] dump_stack+0x4b/0x72 [<ffffffff811d6682>] dump_header+0x87/0x21e [<ffffffffa0646c01>] ? i915_gem_shrinker_oom+0x1a1/0x200 [i915] [<ffffffff8116214b>] oom_kill_process+0x34b/0x3b0 [<ffffffff8116241f>] out_of_memory+0x21f/0x490 [<ffffffff811680f8>] __alloc_pages_nodemask+0x8c8/0x960 [<ffffffff811683ab>] alloc_kmem_pages_node+0x7b/0x150 Can anyone shed any light on what's happening here? Is there a limit to how much video memory the system can access? I thought that was done away with once AGP disappeared but perhaps not. Is there any way to alleviate the problems this issue produces? It's very annoying to be zooming around in Google Maps one moment and then dumped back to the console the next because the kernel killed X11. My system is an Intel DH87MC w/ i7-4770K, kernel 4.3.3. Three monitors, DVI + HDMI + DisplayPort, total res 4960x1600. Many thanks, Adam. _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
