 (from Sept. 13) may be related to this report. It was titled:

Its details were then (some [...] notes added)...

powerpc/GENERIC was then and is now still syscons by default. =
powerpc64/GENERIC64 for .../stable/10/sys/powerpc/conf/GENERIC64 =
switched to vt as the default on Sept. 4 (r271111 MFC'd r265871). At the =
