Created attachment 150771 [details] dmesg of regular boot + startx Trying to run Arch Linux on a Lenovo Y400 with an nvidia GT750M graphics card. When trying to boot the nouveau drivers consistently spit out multiple errors. Computer continues the boot process. Errors also occur whenever I try to run anything with hardware acceleration, such as Xorg. It is a similar output to the one that occurs during boot: PBUS, PIBUS, and PGRAPH errors. Attached is a dmesg log of a regular boot and startx. Also a log of opening up Xorg: http://pastebin.com/w48Dx4qq And a log of opening up weston: http://pastebin.com/1VPFgapP
Did this work with older kernels? If so, a bisect would be useful. Most reports of pgraph timeouts are on GK104/GK106 chips while you have a GK107...
I had errors in 3.16 as well. I'm not sure if the errors are related. I was getting different errors during boot. Here's a few dmesg logs from that kernel. Unresponsive but numlock key works: http://pastebin.com/kzbWdZ0W Boots with one MMIO error: http://pastebin.com/jdSnrzN7 Boots with multiple errors: http://pastebin.com/yRxvh5bB
I belive this is the same bug as https://www.libreoffice.org/bugzilla/show_bug.cgi?id=70354
Yes, this must be https://bugzilla.freedesktop.org/show_bug.cgi?id=70354 and should be fixed now.
