dmesg after glitch happened
I’m seeing weird video glitches on the Intel BayLey Bay –i CRB board, with
Fedora 21, XFCE, and I hope someone can help.
This board has a dual-core ATOM SOC, similar to E3845.
Reproduced on Fedora 21's 3.17.4 and 4.1.13 kernels; and 4.3.0 kernel
(<a href="https://www.kernel.org/pub/linux/kernel/v4.x/linux-4.3.tar.xz">https://www.kernel.org/pub/linux/kernel/v4.x/linux-4.3.tar.xz</a>) also.
To recreate, open an xfce4-term. Generate some output until the cursor is at
the bottom (so the next command will cause scrolling). Wait a few minutes.
Type “ls” (or echo, or most anything; even ssh’ing into the board and doing a
“wall hello”, so that the terminal scrolls, can do it).
An area of the terminal window, and sometimes part of the desktop outside of
the terminal, will be either a solid, text-colored, rectangle, or a “garbled”
area resembling “warped” or torn text, at an odd angle.
Pic attached shoiwng "torn" text.
Hitting Enter or otherwise scrolling again will redraw the window properly;
however, moving another
terminal window over the anomaly and back will NOT cause the glitchy window to
be properly redrawn.
Attached output of intel_reg_dumper and dmesg after it happened; also, output
of
/sys/devices/pci0000:00/0000:00:02.0/rom ("vbios.dump"); and the X log
(Xorg.0.log).
Kernel cmdline included "drm.debug=0xe".
