Are you able to collect a kernel dump?  If so, remove the kld_list
setting and set debug.debugger_on_panic=0 and dev.drm.skip_ddb=1.  Then
manually kldload /boot/modules/i915kms.ko.  If you are running an
INVARIANTS kernel you might be hitting an assertion failure; having the
vmcore would help us debug.
