I'm not sure which tree you based this on, but I got some conflicts in pte-8xx.h using Ben's merge branch. After resolving the conflict, without adding tlbil_va in do_page_fault(), I get the same stuck behavior as before. With tlbil_va, I get this (not sure if it's related to using the wrong base tree): INIT: version 2.85 booting Mounting /proc and /sys dcbz: address:1, dar:30020000! /etc/rc.d/rcS: line 24: 173 Segmentation fault /etc/rc.d/init.d/$i $mode dcbz: address:1, dar:30020000! /etc/rc.d/rcS: line 24: 174 Segmentation fault /etc/rc.d/init.d/$i $mode dcbz: address:1, dar:30020000! /etc/rc.d/rcS: line 24: 175 Segmentation fault /etc/rc.d/init.d/$i $mode dcbz: address:1, dar:30020000! /etc/rc.d/rcS: line 24: 176 Segmentation fault /etc/rc.d/init.d/$i $mode dcbz: address:1, dar:30020000! /etc/rc.d/rcS: line 24: 177 Segmentation fault /etc/rc.d/init.d/$i $mode dcbz: address:1, dar:30020000! /etc/rc.d/rcS: line 24: 178 Segmentation fault /etc/rc.d/init.d/$i $mode dcbz: address:1, dar:30020000! /etc/rc.d/rcS: line 24: 179 Segmentation fault /etc/rc.d/init.d/$i $mode dcbz: address:1, dar:30020000! /etc/rc.d/rcS: line 24: 180 Segmentation fault /etc/rc.d/init.d/$i $mode dcbz: address:1, dar:30020000! /etc/rc.d/rcS: line 24: 181 Segmentation fault /etc/rc.d/init.d/$i $mode dcbz: address:1, dar:30020000! /etc/rc.d/rcS: line 24: 182 Segmentation fault /etc/rc.d/init.d/$i $mode dcbz: address:1, dar:30020000! /etc/rc.d/rcS: line 37: 183 Segmentation fault /etc/rc.d/rc.local $mode INIT: Entering runlevel: 1 dcbz: address:1, dar:30020000! dcbz: address:1, dar:30020000! dcbz: address:1, dar:30020000! dcbz: address:1, dar:30020000! dcbz: address:1, dar:30020000! dcbz: address:1, dar:30020000! dcbz: address:1, dar:30020000! dcbz: address:1, dar:30020000! dcbz: address:1, dar:30020000! dcbz: address:1, dar:30020000!
