There is no error message, the only visible clue I get is different dmesg from
kernel when bootloader loads /netbsd.old
To reiterate: it seems the bootloader sometimes loads /netbsd, and at other
times /netbsd.old kernel, without me explicitly doing anything.
Is it possible there is a bug in bootloder, i.e. when it scans / filesystem for
a kernel to load, it gets confused and loads /netbsd.old kernel when it should
have loaded /netbsd??
