Hi!

Exciting stuff! But sadly still not working for me. All three GENERIC
kernels built from HEAD crash early. I will try to dust off my other O2
in case this one has gone bad. Could you please upload a kernel binary
that works for you?

Here are logs. Crash pc seems to be below the start of kernel text.
