Interesting. I'm not sure what's going on here. The uvm panic looks like a compounded symptom rather than the original problem. Can you try booting with savecore=NO and see if `cat /dev/ksyms' or `nm /dev/ksyms' works? Can you also try rev. 1.103 and see if that makes a difference, just to narrow it down? (No point in trying the other revisions. Unlikely that 1.103 will work if 1.104 doesn't, but will help to confidently narrow it down.)
