Does it ever manage to test the memory it is loaded into? Perhaps by moving itself into different memeory to do this?

I'd be more inclined to look at HW/Sw problems when you are adding something like a 4K screen. Is there sufficient ram? Are you using the same driver for both GPUs? Under beowulf, I couldn't load both the amdgpu and radeon drivers. Have you tried the other way around by setting up 4K, then add the other monitors one by one? Although they are rare, there are some odd problems affecting different HW combos under Linux. I have a problem where my gpu will not boot with two x 2k monitors on DisplayPort cables. It is actually the amdgpu that stack crashes. > > Recommendation is to download and install even a 5.14 (still in beta) > kernel. > > The newest kernel (changed just yesterday) for debian in debian > experimental is a 5.13.?? version. > > Dunno if I want to try a beta kernel (sorta scared to in fact). IME, the worst that will happen is a entirely black screen; thus ssh in to inspect or big red button to restart and then VERY Fast on boot up to intercept the bios(set max timeout prior) to uninstall, or your grub should give the option to go to a prior boot image. Note, at one stage it accumulated them, but now it only keeps current and previous boot image. > Suggestions from y'all? > (Y'all, or at least quite a number of you, have a lot more experience > at this than I do.) > > Please advise. 2c above. ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
[DNG] Advice sought on kernel upgrade
Greetings I am running a fairly old rig on debian testing with 2 gpus and want to run 5 monitors. The 5th is hdmi connected and is a 4k monitor with the other 4 all being 1920x1080. After I installed the 4k monitor I had regular graphics sub-system freezes (won't come out of suspend typically) with a normal being a system reboot at least once every 24 hours. I filed a bug report. Have subsequently unplugged the 4k monitor - - - - a lot of headache rebooting and setting up the machine at least 1x per day. Recommendation is to download and install even a 5.14 (still in beta) kernel. The newest kernel (changed just yesterday) for debian in debian experimental is a 5.13.?? version. Dunno if I want to try a beta kernel (sorta scared to in fact). Suggestions from y'all? (Y'all, or at least quite a number of you, have a lot more experience at this than I do.) Please advise. ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
