One more thing, I'm actually on kernel version 4.19.0.8, but again, this issue started when I upgraded to beowulf.

Re: [DNG] kernel instability 4.9.0-12 with latest update
I've had problems with my machine freezing as well, same symptoms, ever since upgrading to beowulf. The issue for me seems to happen when I run a cpu/ram heavy program, specifically a cpu cryptominer. I've had it happen a number of times, always when mining with max 2 cores, but haven't dedicated the time to report it properly. I did look through various logs in /var/logs but I didn't see anything seemed relevant to the problem. I'll try to reproduce it today and send any relevant logs. What logs specifically would be relevant to this issue? Something relevant to the spectre/meltdown mitigations, I have multithreading turned off in the bios and have had since the vuln's were revealed. Also, 64 bit intel cpu here as well.

What about say limiting ourselves to "PCI"? Just taking a quick spin through newegg, it appears that basically the only unavailable item is a WLAN adapter. Hard drives -> SATA150 or PATA(!!)

[DNG] ibus
Hey, did you hear of ibus? I installed a video-conferencing app on monday, to possibly join a meeting. It came with plenty of dependencies, including something called "ibus". There is a Debian packege for it available on Devuan. According to the poor man page and online documentation, this is an "Intelligent Input Bus". AFAIU, it is a layer between keyboard keystrokes, mouse-moves and mouse-clicks and the input to an application - all user inputs merged in one channel. The goal is to plug into it various interfaces to express complex characters and/or ideograms by composing several keystrokes. Kind of keyboard to Unicode interface. Excellent idea if this was done by using just a command and piping the output to the application needing it. It is implemented on both Mac (therefore free-BSD), and Linux. Dunno how it is made on Free-BSD, but on Linux it is - guess what - a daemon!, further more, applications must talk to this daemon through - guess what - Dbus! I discovered this because, after a reboot, this daemon, normally unseen, suddenly popped up a small window on my desktop to remind me that the new keystroke to perform wtf was shift-space. Actually this daemon was sitting there all the time. I addition, it turned my English keyboard to a US one. Not the real keyboard, of course, but the key mapping, when I type a double-quote, I get an arrowbas! I like US keyboard because I started writing programs 40 years ago when there was only US keyboards and ASCII, but it is impossible to buy an HP laptop with a US keyboard in France; you can only buy one with a keyboard of any European type or Saoudian. I chose UK which is the closest to US. After uninstalling ibus, and dependencies, my keyboard mapping is correct again. There's now a fashion of doing all innovations in a complicated way. It seems developpers have become unable to think simple. This is terribly disapointing. Didier ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

Probably . The question is exactly what peripherals were you thinking on running off it? Some examples from here; My PIO NEC Pinwriter printers, which are very nice for textt and basic graphic output, suffer from lack of ribbons because the driver foam in the ribbon cartridges have dis-intergrated with age. My PIO/SIO Gestetner Canon SX2 laser printer has flat rollers. I shudder to think what the condition of my QIC (PIO) & DAT tapes (SCSI is like. It is bad enough that the DLT-IV drives are both cactus and will cost more to repair than purchasing a new LTO-6 drive. There is probably other stuff buried away waiting for the next major clean out. The real problem with old stuff is that if it doesn't work then it is usually isn't economic to repair and that the newer stuff is so much better and cheaper. This was brought home when someone gifted me an Intergraph 5RU Quad Zeon system and two similar sized external hard disk boxen holding 12 FW scsi seagate barracutta hard drives. Very nice kit, until I costed the price of the needed two FW scsi cables to join both boxen to the CPU boxen. It was far cheaper to buy double the hard disk capacity in new SATA drives. So, even if it was built, there is probably going to be negligible demand for it for that reason. Having started my "IT" career when it was called EDP, I am all for alternative hardware and for this reason have only purchased AMD kit(for better or worse)for a decade, so I'd gladly welcome another alternative HW system, but RISC(IBM) and very wary. ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
