Putting the names back to default. Still no luck, it looks at the sd card for about 250 milliseconds and quits, no video or further keyboard response.
This acts exactly the same as it did after I had allowed apt to update a bunch of stuff in the /boot partition on the morning of May 2, so I have not allowed this card to be updated till now. Now, out of 6 or 7 sd cards, I am down to only having one that will boot it. Again. Currently the boot dir looks like this: root@coyote:/media/usb1# ls -l total 27144 -rwxr-xr-x 1 root root 12829 May 12 2016 bcm2708-rpi-b.dtb -rwxr-xr-x 1 root root 13092 May 12 2016 bcm2708-rpi-b-plus.dtb -rwxr-xr-x 1 root root 12865 May 12 2016 bcm2708-rpi-cm.dtb -rwxr-xr-x 1 root root 14175 May 11 2016 bcm2709-rpi-2-b.dtb -rwxr-xr-x 1 root root 14845 May 11 2016 bcm2710-rpi-3-b.dtb -rwxr-xr-x 1 root root 15350 Dec 22 02:46 bcm2710-rpi-cm3.dtb -rwxr-xr-x 1 root root 17932 Dec 22 02:46 bootcode.bin -rwxr-xr-x 1 root root 300 Dec 22 02:48 cmdline.txt -rwxr-xr-x 1 root root 131097 Mar 7 2016 config-4.4.4-rt9-v7+.old -rwxr-xr-x 1 root root 1915 May 13 12:54 config.txt -rwxr-xr-x 1 root root 18693 Dec 22 02:46 COPYING.linux drwxr-xr-x 4 root root 8192 Dec 22 15:55 dtbs_rt -rwxr-xr-x 1 root root 2535 Dec 22 02:46 fixup_cd.dat -rwxr-xr-x 1 root root 6622 Dec 22 02:46 fixup.dat -rwxr-xr-x 1 root root 9753 Dec 22 02:46 fixup_db.dat -rwxr-xr-x 1 root root 9753 Dec 22 02:46 fixup_x.dat -rwxr-xr-x 1 root root 145 Sep 23 2016 issue.txt -rwxr-xr-x 1 root root 4268272 May 11 2016 kernel7.img -rwxr-xr-x 1 root root 4231624 May 12 2016 kernel.img -rwxr-xr-x 1 root root 4376248 Mar 7 2016 kernel_rt-4.4.4-rt9-v7+.img -rwxr-xr-x 1 root root 1494 Dec 22 02:46 LICENCE.broadcom -rwxr-xr-x 1 root root 18974 Sep 23 2016 LICENSE.oracle drwxr-xr-x 2 root root 49152 May 13 12:24 overlays -rwxr-xr-x 1 root root 634532 Dec 22 02:46 start_cd.elf -rwxr-xr-x 1 root root 4956996 Dec 22 02:46 start_db.elf -rwxr-xr-x 1 root root 2823396 Dec 22 02:46 start.elf -rwxr-xr-x 1 root root 3906116 Dec 22 02:46 start_x.elf -rwxr-xr-x 1 root root 2107458 Mar 7 2016 System.map-4.4.4-rt9-v7+.old I'll redo it just for s&g. In the meantime I'm re-writing that card with the April 10th image just to see if it will even boot. Looks like dd is done, brb. Boots, input not supported. I was going to login from here and fix /boot/config.txt, I think it needs the monitor specified. No, can't do that yet, network-mangler at work, got to emasculate that puppy. Put my hosts, resolv.conf, and interfaces file, makeing resolv.conf immutable while I'm at it, maybe nuke resolvconf too. And fix /boot/cmdline.txt. Failed, no boot. Put card in another pi, booted but no video. Found a card that did boot to good video, copied its config.txt to dead tree, booted the test card again, fixed config.txt. Rebooted, good video, so now I'm doing an update w/o the new kernel and without the wolfram engine, which made it about 120 megs into the 240 meg download and died. Wash, rinse and repeat, times out on the remainder of that file, unmark it, and its stumbling along again. If when this is all done, the card gets moved to the pi I have bolted into the box lid. If it doesn't boot, change the pi. But this upgrade will take another couple of hours, so I'll post this. That attack they're talking about on the news sites sure is reducing the net's traffic. Very slow today. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
