On these systems you are supposed to have auto-update disabled and be conservative (easy to say, hard to do). Afaik, doing an "apt-get upgrade" will not upgrade the kernel. You normally have to do "dist-upgrade" for kernel updates. For the Pi, I always make a card image on my local host of the latest running version using: # dd if=/dev/sdX bs=4M | gzip > piimg-XYZ-$(date '+%Y%m%d%H%M%S').img.gz (I usually add some more identifying stuff to the filename part XYZ to keep track what is in the image) That way I do not have to start from scratch each time something bad happens (or the SD card dies). BTW, I have an sshfs running where the sources are. That way I'm not trashing the SD card too soon. Fwiw, Gene, I've got a Pi3 running: $ uname -a Linux picnc 4.9.30-rt20-v7+ #1 SMP PREEMPT RT Sun May 28 09:40:46 CEST 2017 armv7l GNU/Linux And, boy is the Pi3 a heat-generator. Several crashes with the environment here (today) at 27 degrees C and doing linuxcnc compiles. Finally added a heatsink. Now, if I can get linuxcnc to play nice... It is not happy about my setup. Doing deb-package creation is too much of a pain. -- Greetings Bertho (disclaimers are disclaimed) ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
