I saw an identical problem when I booted a kernel from yesterday with kernel 
modules from a week or so earlier, only mine froze before getting to the 
Timecounter line, rather, immediately after the vga0 line.  Perhaps we're 
looking at an issue with mixing modules with a kernel from before/after the 
compiler upgrade?
