Is 64 bit Haiku broken?

Starting with hrev46732 I have not been able to boot 64 bit Haiku. The installer goes into KDL immediately after the boot screen appears. Until now, my normal procedure is to write the anyboot image to a USB drive, then boot with failsafe video mode enabled at 800x600 resolution.
Can anybody else verify if there is a problem, and suggest any steps I can take to circumvent the boot issue?

Same issue here - any system I run it on fails to boot USB or CD. Looks like its still unusable.
