 When it reboots, are you able to get the preceding boot's dmesg?
 
 Can you try building a kernel with
 
 options 	DDB_ONPANIC=1
 options 	DDB_COMMANDONENTER="bt;ps;sync"
 
 and see if it produces a crash dump or dmesg from the preceding boot?
 Once it reboots, at the bootloader prompt, you can do
 
 > userconf disable i915drmkms
 
 to boot without the i915 driver.
 
 Alternatively, do you have a serial console, e.g. via Intel AMT?  Can
 you get the console output via that?
