Switching back to X11 can take several seconds and a few more seconds before X11 becomes responsive. After kernel oops the mouse pointer can dissapear repeatedly, taking again few seconds for X11 to become responsive and for mouse pointer to reappear. Again a "flip_done time out" is seen in "dmesg" every time it happens (attachment). No issues occur trying to switch several times between TTY2 and X11(DRI3, SNA) on an Intel Core-i3 NUC with same Arch Linux and "4.10.0-rc7-drmtip" kernel. ---=[ system info ]=--- distro: Arch Linux, arch: x86_64 linux: 4.10.0-rc7-drmtip (git#2699547: integration manifest) xf86-video-intel: 1:2.99.917+753+g9fe04af4-1 mesa: 13.0.4-1 xorg-server: 1.19.1-1 kernel-param: i915.modeset=1 drm.debug=0x1e machine-1: Lenovo ThinkPad T520, model 42435JG cpu: CPU0: Intel(R) Core(TM) i7-2640M CPU @ 2.80GHz (family: 0x6, model: 0x2a, stepping: 0x7) lspci: 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) machine-2: Intel NUC5i3RYB CPU0: Intel(R) Core(TM) i3-5010U CPU @ 2.10GHz (family: 0x6, model: 0x3d, stepping: 0x4) lspci: 00:02.0 VGA compatible controller: Intel Corporation HD Graphics 5500 (rev 09)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
