It failed to start three of the four cpus on the kernels from 5.10 and 5.11 when running Tumbleweed snapshot 20210328. It still runs and boots all the way to the graphical environment, however performance is greatly diminished. -- You are receiving this mail because: You are on the CC list for the bug.
