well, if it was a BUG()/BUG_ON() you should have/see
a file name and line number where it triggered

if it was some invalid address or bad pointer, then
you should have that written too, which also would
give a lot of helpful information ...

could you try to collect a complete bootup and oops
log via remote console?

could you also give the stable branch 2.0.1 a try
just to see if that one works?
