When loading the module via kld_list in /etc/rc.conf at boot, screen goes blank and system stops respon= ding until a power cycle. If booting without loading the module and loading it w= ith kldload manually, the screen goes blank and reboots after some time. In the latter case a crashdump is found at the next boot. Hardware is an Acer C720 Chromebook, using a Celeron 2955U. The graphics controller shows in pciconf -lv as "Haswell-ULT Integrated Graphics Controller". Kernel config is based on GENERIC, but with options WITNESS and WITNESS_SKIPSPIN added. I don't know much about debugging kernel dumps, but if someone tells me how= to do it I'm ready to try getting data out of the existing dump.
