When I looked closer, nothing seemed to make sense so here is another
log with stack unwinder, frame pointer etc etc

PANIC: early exception rip ffffffff8095a873 error 0 cr2 5cf0

Call Trace:
 [<ffffffff8020b174>] dump_trace+0xb6/0x3d8
 [<ffffffff8020b4d2>] show_trace+0x3c/0x52
 [<ffffffff8020b4fd>] dump_stack+0x15/0x17
 [<ffffffff802001e7>]
DWARF2 unwinder stuck at 0xffffffff802001e7
Leftover inexact backtrace:
 [<ffffffff8095a873>] reserve_bootmem_node+0x1/0x12
 [<ffffffff8096114f>] acpi_table_parse+0x4f/0x69
 [<ffffffff80955f91>] reserve_bootmem_generic+0x73/0x9e
 [<ffffffff8094edd3>] setup_arch+0x301/0x49c
 [<ffffffff8094855f>] start_kernel+0x6c/0x30b
 [<ffffffff80948144>] _sinittext+0x144/0x14b

RIP reserve_bootmem_node+0x1/0x12

Will keep kicking.
