Blah. My troubles with the ryzen5 continue. After freezing once a day for weeks, it finally totally froze. I have to reinstall.
ps. It's super-horrible reinstalling because the Debian Installer doesn't work right now. It won't install grub. Then I ran into the fact that moving to 'unstable' brings up the worst kernel for amdgpu and won't boot. Then 'stable' doesn't have 'kernel-package'. I'm trying the 'buster' install and going right to the latest kernel. Blah.
ps. So, the sequence is -- install debian with the buster alpha. Load kernel-package and other junk. Get the latest 4.17.9 and compile it. Don't forget to install libssl-dev, or you're hosed, and never know why.
Then the stupid thing works, for a while perhaps. I should take more backups, but this is my experimental machine. I run really weird stuff on it.
pps. still freezing
14.17.9 is worse than ever, trying another one.
14.18 rc6 is working, and I can't crash it. However, all of these things have gone bad in a couple days. Must be memory leaks.
now it is freezing
