One of these board just stopped replying to pings and is not accessible through ssh, but each night it sends an email telling me there are updates for that board. I'm running Devuan Beowulf with an Armbian kernel and a "performance" governor. Someone said that switching to "performance" seems to resolve the issue.

In my opinion, yes. What if a browser didn't remove the high resolution timers? What if other software, currently considered "trusted", acts as a vehicle for the exploit? What if the badguys know more about exploits than you? Making sure you use the right browsers and only trusted apps in the face of a virus like this strikes me like wearing a mask and using plenty of hand cleaner and then hanging around in a meat packing plant. Yeah, you've taken all the precautions you know to take, but you've placed yourself right in the flight path of the virus. There's something else too. The OP measured 32% slowdown on one activity. We don't know whether that kind of performance is common to most activities. Removing protection against known exploits to cure a problem with an unknown cause and an unknown range is the ultimate in proceeding on an untested assumption. Until the root cause is known, no solution should be applied, and diagnostic tests should be performed in a safe manner.

Re: [DNG] Orange Pi Zero/Orange Pi PC
Citando richard lucassen via Dng : No, even cronjobs do not work or give segmentation fault. It must be the hardware. There must be a batch with these issues, I'm not the only one BTW. I wonder if it has got something to do with the wifi chip. A crash occurs earlier if you load the kernel module. That seems to be some problem with the rtc oscillator or so..hardware probably( I got a problem with my rpiv2 with its 26Mhz oscillator, its similar in nature with what you describe.. The ASCII image is ok, but I updated this image to Beowulf and I used Armbian kernel with it. But I fear it will crash again. Anyway, I just got some Rasberry Pi Zero-W now and I think I will stay with these boards. Remember I have also Orange Pi PC, different CPU, suffering from the same issues. The devuan images are tested, And so, I personally, advise always to stick with its kernels, but anyone is free to mix what they want too :) That in so many boards,... it could be a batch that went wrong, or badly designed boards.. ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

Hi, Lately, when I attempt to update Devuan Boewulf, apt-get fails complaining that I should explicitly accept the repositories. Reading 'man apt-secure' talks about changes in Debian's security which has the aim to reinforce package security further. While this is good news, it is proving also to be a headache.
