If possible I'll make a debug kernel specifically to troubleshoot this. A= lso if there are specific files or modules that anyone might consider worth my = time to look at closely, that would be appreciated (thanks). This is the CPU I'll focus on (from dmesg) CPU: AMD Ryzen 5 2600 Six-Core Processor (3393.71-MHz K8-class = CPU) --=20 You are receiving this mail because: You are the assignee for the bug.=
