Things tried.

# For hangcheck_ring_idle error,
[drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... blt ring
idle [waiting on 17594, at 17594], missed IRQ?

# the following work-around works on my system,
    pathi915Sem="/sys/module/i915/parameters/semaphores"
    echo "1" | sudo tee $pathi915Sem  > /dev/null

# Then tried to turn off the NVIDIA, with the ACPI call that works on my
system,
    sudo insmod acpi_call.ko
    m="\_SB.PCI0.PEG0.PEGP._OFF"
    pathAcpiCall=/proc/acpi/call
    echo $m > $pathAcpiCall

# But, after that ACPI call is done, the system tends to freeze after a
short while.
# Typically the freeze is after some idle time when the display has blanked;
keyboard seems to die after some time.
# I think I have seen a freeze while working too -- need more samples;
inputs/suggestions are welcome.
