If you'd care to try to debug this further, that would be great. You should add back the failing options to a test kernel, configure it with -g so as to get a kernel.debug with symbols, boot it, and note the faulting pc. Then run gdb on kernel.debug and say "l *<faulting pc>" Eg: (kgdb) l *0xfffffc00003a3270 This should display the problematic line of source code. Thanks!
