That's current. What does 'nvsetenv' (no arguments) report?

Please run strace nvsetenv boot-device and send the output of that by PM.

Corrupted nvram should be detected by the nv load code and trigger an
error. Maybe the stored length of a packed string got corrupted; that's
about the only thing that should throw a segfault.
