I have managed to get freezes on linux-4.19.120-gentoo as well, after using CPU pinning together with RR scheduling policy and priority to 1 for all vCPU threads. After removing the commit 47c61b3955cf712cadfc25635bf9bc174af030ea it seems like the system is indeed working without freezing. I will continue testing and updating as I get more information. -- You are receiving this mail because: You are watching the assignee of the bug.
