I suspect that if I swapped it for some other Some want to believe and that's fine but AMD story is and always was bullshit and here's why: My EVGA SuperNOVA 750 G3 & Corsair RM650i are modern and C6/"haswell" compliant PSUs. There's plenty of other people with a variety of new and old and cheap and expensive PSUs who are affected by this TOTAL SCANDAL bug.
The new Power Supply option in BIOS set to Typical does fix it all combinations of Ryzen motherboards/CPUs/PSUs I've tried. The root cause could be a combination of motherboard/CPU/PSU but my guess is that it's got more to do with motherboard voltage regulators and less to do with PSUs. Buying a new PSU isn't a viable option anyway, what are you going do to? buy every single PSU on the market and hope you stumble upon one that works with the "low current" power supply option in BIOS after trying 20 that don't? If you sell a computer monitor that does not work properly on 19 out of 20 graphics cards then it's not the graphics cards that are to blame, you're selling a defective product. The Typical Idle setting is a fine solution if you know about it, so there's that. Works for me. I do feel sorry for poor noobs who don't know and pull their hairs for hours before discovering the shocking truth, though. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1690085 Title: Ryzen 1800X freeze - rcu_sched detected stalls on CPUs/tasks To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1690085/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
