weird backtrace during kernel panic, possibly due to mapping symbols

[Conor Dooley]

Hey!

I posted this weird backtrace on IRC over the weekend & Palmer thinks
the blame lies with binutils 2.40 emitting mapping symbols that the
stack dumper cannot handle:

[<ffffffff80003406>] ret_from_fork+0x6/0x1c

The panic itself is just a missing rootfs, so nothing to be concerned
about :)

Cheers,
Conor.
