4.8-S crashes during boot in USB code

You'll probably find that when you take out the crypto and FAST_IPSEC
options from your kernel config, it will boot perfectly.  There's a bug
that causes a panic in uhci.c when crypto is enabled.  A patch is already
in CVS in the MAIN branch.  See this link:

Yes, generic should boot just fine, as long as crypto isn't enabled.
