 There's a definite improvement with 8.99.31 vs. 8.0_STABLE. That is,
 with -current it successfully completes booting, where it simply froze
 before. The issue now is that the console is unusable: at a certain
 point in the process, it changes to a white cursor at the bottom left
 of the screen which moves back and forth a bit over time, but that's
 it. I'm able to ssh into the machine and use it remotely, though.
 
 Relevant dmesg excerpts from 8.99.31 are:
