The panic is the real problem, not the warning message.  It's possible
that they're related, but certainly not obvious.  Can you capture any
information about the panic with a serial console, netconsole, or even
a digital photo or movie?

It sounds like this is a regression, so it will be useful to know the
newest kernel that works correctly and the oldest one that fails.
