Confirming this issue, Ryzen 2500U on HP Notebook 15-db0229ur. - Disabling C-State C6 partially solves the problem - Latest BIOS from manufacturer (F.11 Rev.A) - unable to access any of advanced settings!
Also bug here: https://bugzilla.redhat.com/show_bug.cgi?id=1562530 Disabling C6 states is not a fix it really. It's C6 idle state still, disabling it increases power consumption of CPU at least by 80% in idle state. This is certainly a kernel issue. Random freezes are random, they cause massive data loss as all you can do is to force reboot the laptop. AMD did publish an errata report, pointing that this may be fixed at software level (page 63). https://www.amd.com/system/files/TechDocs/55449_Fam_17h_M_00h-0Fh_Rev_Guide.pdf -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1772081 Title: HP x360 - Ryzen 2500U Locks up Status in linux package in Ubuntu: Incomplete Bug description: Hi, I have an HP x360 Ryzen 2500u.
