Sorry about the build problems, will fixup. Don't know what is causing the error though, works just fine on 2.4 :( Assuming you fixup this error: arch/powerpc/kernel/head_8xx.S:577: undefined reference to `DARfix' with a "b DARFix" I can only guess and I don't have a good guess even :( You could back out 8xx: start using dcbX instructions in various copy routines to see if it is the dcbX insn that is causing the error. > > INIT: version 2.85 booting > Mounting /proc and /sys > Starting the hotplug events dispatcher udevd > udevd[177]: add_to_rules: unknown key 'MODALIAS' in > /etc/udev/rules.d/60-pcmcia.rules:4 > udevd[177]: add_to_rules: unknown key 'MODALIAS' in > /etc/udev/rules.d/60-pcmcia.rules:10 > udevd[177]: add_to_rules: unknown key 'MODALIAS' in > /etc/udev/rules.d/60-pcmcia.rules:14 > Synthesizing initial hotplug events > /etc/rc.d/init.d/udev: line 41: 187 Segmentation fault udevsettle > --timeout=300 This looks like the first error? > Setting the hostname to 8xx > Running depmod > WARNING: Couldn't open directory /lib/modules/2.6.31-08384-g2cb4b47-dirty: No > such file or directory > FATAL: Could not open /lib/modules/2.6.31-08384-g2cb4b47-dirty/ > modules.dep.tempfor writing: No such file or directory > Mounting filesystems > BUG: soft lockup - CPU#0 stuck for 61s!
