Until this is addressed you > can checkout an earlier revision or revert r273582 locally. I have committed a workaround for this issue in r274382. The vt(4) EFI framebuffer driver makes use of kernel infrastructure in a way that is not correct, but works in practice, and this was caught by a new assertion added in r273582. My change loosens the assertion to allow efifb's use for now. We will need to fix the early framebuffer implementation in a subsequent change. -Ed
