And it locked up solid the first time I started the build.. After restarting the build as needed, I've built a working kernel natively. Nice work Peter! I've got 2 weird quirks which I was wonder if are specific to my hardware -- - there's no TOY (or TOD) clock read at boot: # uptime 12:02AM up 3 mins, 0 users, load averages: 0.05, 0.06, 0.03 # date Thu Jan 1 00:02:33 GMT 1970 - reboot locks the machine up: # reboot Waiting (max 60 seconds) for system process `vnlru' to stop...stopped Waiting (max 60 seconds) for system process `bufdaemon' to stop...stopped Waiting (max 60 seconds) for system process `syncer' to stop...stopped syncing disks... done Uptime: 21m21s Rebooting... ok 0 At this point, it looks good, but openfirmware won't take any input. Both of these are very minor .. I was just curious. Thanks, Drew To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ppc" in the body of the message
