error log

Occasional constant GPU hangs on Clevo N130WU, even after reboots, unless shut
down and leaving it for a while (?). Internal display screen freezes, maybe a
black jagged triangle is drawn across top-right of desktop, recovers, then
freezes. Intermittent, unreproducable, happens by opening a menu or mouse-over
the panel, or using Firefox or MPV in MATE (both use GPU acceleration, MATE
doesn't?). In x86_64 Mint 18.3 Cinnamon LiveUSB & Installed (and Fedora 27
Cinnamon LiveUSB). Updated with Linux 4.16.3 and kbl_dmc_ver1_04 and
ppa:oibaf/graphics-drivers (Mesa 18.2.0-devel, libdrm 2.4.91,
xserver-xorg-video-intel uninstalled, etc). GPU crash dumps attached, unable to
dump VBIOS "cat: '/sys/devices/pci0000:00/0000:00:02.0/rom': Input/output
error", "stolen memory" not in BIOS (?). I am not technically skilled but
trying. Thank you

Relevant dmesg messages:
Reducing the compressed framebuffer size. This may lead to less power savings
than a non-reduced-size. Try to increase stolen memory size if available in
BIOS.
