Can you check something else as well?

Compile a kernel with:

-----
# Give us a choice of fonts based on monitor size
#options        FONT_BOLD8x16
#options        FONT_BOLD16x32
options         FONT_SPLEEN12x24

ie. with a non-standard font. On my Asus X202E laptop (in CSM mode) the
system comes up OK, but, X hangs as soon as you start it with this
message being repeated every 3 secs. in the logs. (Power-off using the
power button works correctly and the system does an orderly shutdown
which is why I could collect these logs.)

I don't know if this is caused by the new DRM, or if the new code is just
exacerbating a pre-existing condition (the pre-newdrm kernel used to
reboot immediately after being loaded if compiled with any of these
fonts instead of the standard ones):

  FONT_DROID_SANS_MONO9x18
  FONT_DROID_SANS_MONO10x20
  FONT_DROID_SANS_MONO12x22

Thanks,
