Expected, I havn't not tried to fix the missing tlbil_va(). That is different problem that you and Ben needs to sort out. > With tlbil_va, I get this (not sure > if it's related to using the wrong base tree): Could be the debug code doing something bad or the "Fixup DAR from buggy dcbX instructions". Could you back that one out? and if that does not help, backout: "start using dcbX instructions in various copy routines" too. > > 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! > INIT: Id "l1" respawning too fast: disabled for 5 minutes > INIT: no more processes left in this runlevel > > -Scott > > _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
