Hello,
Glad to report good stable jitter result with Ryzen 5-3500U on ordinary 400USD HP laptop. OS - Mint 20 with 5.0 kernel, Linuxcnc 2.8. Maximum base thread jitter was 24us and servo jitter was 13us during the night under the load. isolcpus=6,7 and virtual technology enabled in BIOS. VT disabled has been causing twice a minute 800us jitter.
