--- Comment #26 from Dennis Clarke <dcla...@blastwave.org> --- (In reply to Francis Little from comment #25) I am working with a PowerMac G5 here with 8GB of memory and just a very trivial baseline install from the 12-RELEASE dvd. That means nothing from ports and not even pkg other than the stub in place. So it took me a moment to figure out the command line for "fetch" which seems to be a little brother to big bad 'wget' : hydra# pwd /usr/src/artifact hydra# hydra# fetch --no-verify-peer https://artifact.ci.freebsd.org/snapshot/head/r350074/powerpc/powerpc64/kernel.txz kernel.txz 24 MB 12 MBps 02s hydra# ls kernel.txz hydra# xz -dc kernel.txz | tar -xf - hydra# ls boot kernel.txz usr hydra# hydra# hydra# uname -a FreeBSD hydra 12.0-RELEASE FreeBSD 12.0-RELEASE r341666 GENERIC powerpc hydra# mv /boot/kernel /boot/kernel_r341666 hydra# mv boot/kernel /boot hydra# That should be all I need. However what is this stuff ? hydra# ls -la usr/lib/debug/boot/kernel/ total 824 drwxr-xr-x 2 root wheel 512 Jul 17 02:22 . drwxr-xr-x 3 root wheel 512 Jul 17 02:22 .. -r-xr-xr-x 1 root wheel 543800 Jul 17 02:22 fuse.ko -r-xr-xr-x 1 root wheel 121696 Jul 17 02:22 if_tap.ko -r-xr-xr-x 1 root wheel 121696 Jul 17 02:22 if_tun.ko hydra# I have no idea about those. I have my own already and I will save them : hydra# hydra# cp -p /usr/lib/debug/boot/kernel/fuse.ko /usr/lib/debug/boot/kernel/fuse.ko_mine hydra# cp -p /usr/lib/debug/boot/kernel/if_tap.ko /usr/lib/debug/boot/kernel/if_tap.ko_mine hydra# cp -p /usr/lib/debug/boot/kernel/if_tun.ko /usr/lib/debug/boot/kernel/if_tun.ko_mine hydra# hydra# cp -p usr/lib/debug/boot/kernel/* /usr/lib/debug/boot/kernel/ hydra# Fine so .. that should be it for this "artifact" kernel stuff that we did not need to compile ourselves but you and I are clearly hitting a panic over and over. So I reboot now and interrupt the boot loader to set kern.smp.disabled=1 and guess what ? The damn thing boots. Moments like this cause me to lose faith in compilers and source code. Where was this kernel compiled and why is it different from what we have carefully home baked with just "make kernel" ? I can ssh in from another machine just fine and look around : hydra# hydra# uname -a FreeBSD hydra 13.0-CURRENT FreeBSD 13.0-CURRENT r350074 GENERIC powerpc hydra# hydra# sysctl -a | grep 'smp' kern.smp.maxid: 3 kern.smp.maxcpus: 256 kern.smp.active: 0 kern.smp.disabled: 1 kern.smp.cpus: 1 kern.smp.threads_per_core: 1 kern.smp.cores: 1 kern.smp.topology: 0 kern.smp.forward_signal_enabled: 1 "devfs","crossmp" hydra# hydra# cat /etc/rc.conf clear_tmp_enable="YES" syslogd_flags="-ss" hostname="hydra" ifconfig_bge0="inet 172.16.35.8 netmask 0xffffffc0" defaultrouter="172.16.35.1" sshd_enable="YES" ntpd_enable="YES" # Set dumpdev to "AUTO" to enable crash dumps, "NO" to disable dumpdev="AUTO" hydra# At this point I want to try a "shutdown -r 'now' " and see what smoke comes out. hydra# hydra# shutdown -r 'now' Shutdown NOW! shutdown: [pid 1074] hydra# *** FINAL System shutdown message from dclarke@hydra *** System going down IMMEDIATELY System shutdown time has arrived Connection to 172.16.35.8 closed by remote host. Connection to 172.16.35.8 closed. . . . Now I watch as the machine does the usual openfirmware bits and just let it boot with zero input from me. Boots fine. All cores available : hydra# uname -a FreeBSD hydra 13.0-CURRENT FreeBSD 13.0-CURRENT r350074 GENERIC powerpc hydra# uptime 8:10PM up 58 secs, 1 user, load averages: 0.57, 0.21, 0.08 hydra# sysctl -a | grep 'smp' kern.smp.maxid: 3 kern.smp.maxcpus: 256 kern.smp.active: 1 kern.smp.disabled: 0 kern.smp.cpus: 4 kern.smp.threads_per_core: 1 kern.smp.cores: 4 kern.smp.topology: 0 kern.smp.forward_signal_enabled: 1 "devfs","crossmp" hydra# baffled.
