Bug#875631: linux: [i915/iron lake] Screen flickering instability in 4.9, 4.11 (3.16, 4.12 OK)
Source: linux
Version: 4.9.30-2
Control: fixed -1 3.16.43-2+deb8u2
Control: fixed -1 4.12.6-1
Control: found -1 4.11.6-1
As I mentioned before on IRC, my system with Iron Lake graphics
and a Pentium P6200 (a ThinkPad Edge 15, from 2010 IIRC) is
unstable in stretch. It used to work fine in jessie.
With stretch, the screen flickers, or a horizontal line appears
on the screen, usually when pressing keys (interrupts?). In dmesg
a warning appears:
Sep 11 13:10:43 thinkpad-parents kernel: [drm:ironlake_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun
Sep 11 13:10:43 thinkpad-parents kernel: [drm:ironlake_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrun
And sometimes the system would just hang.
Tested versions:
* jessie 3.16: stable
* xenial 4.4: still flickers, but does not seem to hang
* stretch 4.9.30: flickers and crashes
* stretch 4.9.47: seems to flicker more
* 4.11.6-1: flickers, not sure if crashes
* 4.12.6-1: no flickering
