我正在运行 Debian 测试（最后更新时间：2017 年 10 月 31 日），当我通过浏览器从 Twitch 或 iView 全屏播放视频时，它会挂起 GPU，因此 GUI 全部冻结。
我拥有的计算机是 '上平方' 使用英特尔 505HD。
不过内核仍在运行，因为我仍然可以通过 ssh 访问它。
我正在运行内核 4.12
Linux BB-8 4.12.0-0.bpo.2-amd64 #1 SMP Debian 4.12.13-1~bpo9+1 (2017-09-28) x86_64 GNU/Linux
我还在我的 /etc/X11/xorg.conf 中使用了视频撕裂的解决方法
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "TearFree" "true"
End
错误消息（dmesg 输出）；

这很容易复制，可以通过全屏加载 twitch 来完成，大约 5 分钟后它就会挂起。有时是在开始时，有时是经过一段时间。
我怎样才能解决这个问题？
更新
我将内核更新到4.13，但这并没有解决问题。
然后我删除了 TearFree 选项。我相信这确实有帮助，但后来我流泪了。
** 错误 ** 这是一个略有不同的错误，但结果仍然相同，因为它冻结了 GUI 屏幕，并且必须使用 Magic Keys 来重新启动。

答案1
请以 root 身份执行：
- 编辑
/etc/default/grub GRUB_CMDLINE_LINUX找到以和append开头的行i915.enable_rc6=0，例如：GRUB_CMDLINE_LINUX="splash quiet i915.enable_rc6=0"- 执行：
update-grub - 重启
- （可选步骤）执行
systool -m i915 -av | grep enable_rc6以检查您是否正确设置了该选项
答案2
我有 Jumper Ezbook3 Pro、Linux Mint 18.3 并且有类似的错误： i915 0000:00:02.0: 在 gpu 挂起后重置 bcs0
就我而言，当我启动 OBS studio 等图形密集型任务时，就会发生此类错误。由于 GPU 挂起，Xorg 每 10-20 秒就会冻结一秒。我注意到，只有当笔记本电脑依靠电池供电时才会发生这种情况。
所以就我而言，它一定是电池有故障，无法为满载的 CPU 和 GPU 提供足够的电量。
