启动时出现DRM错误


9

我最近在启动时注意到了这些错误(它们在每次启动时都会发生):

Jun 29 08:07:09 MATRIX kernel: [   10.773473] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun
Jun 29 08:07:09 MATRIX kernel: [   10.773876] [drm:intel_set_pch_fifo_underrun_reporting [i915]] *ERROR* uncleared pch fifo underrun on pch transcoder A
Jun 29 08:07:09 MATRIX kernel: [   10.773895] [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrun

它们是什么意思,我应该怎么做?


操作系统信息:

Description:    Ubuntu 15.04
Release:    15.04
intel  drm

内核错误跟踪器上有此错误的条目: bugzilla.kernel.org/show_bug.cgi?id=79261看来此错误消息应该只是调试消息,所以没什么严重的。

@tommyk:也许发布一个解释作为答案。

以我的经验,我是通过在启用UEFI“安全启动”的情况下安装ubuntu,然后尝试在禁用“安全启动”的情况下启动而导致此问题的,如果禁用了该功能,请尝试在BIOS中重新启用它。
