I'm using debian jessie 8.1 and running the Chromium browser, even after a while hangs not only the browser as the entire system, and to restart the machine, entering a tty. Once I realized this, it opens a terminal with the command "journalctl -f" to the log monitor, and also the command "tail -f /var/log/Xorg.0.log" to monitor the X log output, entratando I only have one line from the log and dmesg nothing more: Jul 26 18:39:45 debian kernel: [drm: i915_hangcheck_elapsed] * ERROR * Hangcheck elapsed timer ... render ring idle Monitoring with journalctl and dmesg only have this single line and nothing else, in Xorg.0.log files does not leave any rows. I was using Gnome and also had these problems with more frequency, but I thought it is the fault of interface, entretando see that it's not, it's probably a kernel bug. I also tried the Arch Wiki tips, but to no avail https://wiki.archlinux.org/index.php/Intel_graphics I leave here the result of the lspci command, if necessary. lspci -s 00:02.0 -v 00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03) (prog-if 00 [VGA controller]) Subsystem: Lenovo Device 3602 Flags: bus master, fast devsel, latency 0, IRQ 46 Memory at fe400000 (64-bit, non-prefetchable) [size=4M] Memory at e0000000 (64-bit, prefetchable) [size=256M] I/O ports at dc00 [size=8] Expansion ROM at <unassigned> [disabled] Capabilities: <access denied> Kernel driver in use: i915
We seem to have neglected this bug. Apologies. If the problem persists with latest kernels, please file a bug at the freedesktop.org bugzilla [1], referencing this bug. Thank you. [1] https://bugs.freedesktop.org/enter_bug.cgi?product=DRI&component=DRM/Intel
