I don't have a netbsd.gdb for that kernel. I tried guessing the time
and recreating it, but didn't manage to, sorry. (I had updated to get

(gdb) x/i  usb_allocmem_flags+0x6c
   0xffffffff808dbe2c <usb_allocmem_flags+108>: cmp    %rbx,(%rcx)

Does this help?

I have the kernel (without symbols) and the crash dump if you want to
