Low memory page fault. I saw the same thing myself. It turns out, though, that I was using COPTFLAGS= -march=pentium -Os -pipe to compile my kernel. When I used the stock opt flags of COPTFLAGS= -O -pipe to compile my kernel, my machine booted OK. It appears as though some changes were put in the tree that are sensitive to optimizations above -O -pipe. My machine never behaved this way before with high optimizations until the new changes were put into -current about 1 or 2 days ago. - Donn To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
