Hi all, I've started bringing up FreeBSD-HEAD on the AR9344 which is a MIPS 74k core. It panics shortly after boot, in the invalidation code. We've traced it down thus far to duplicate entries in the TLB. An example TLB list: http://pastebin.ca/2423778 Now, I think it's something in MipsDoTLBMiss or MipsTLBInvalidException in exception.S. I'm out of my depth here. Could I please get some help in figuring out what's going on? Thanks! -adrian
