https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D219399 --- Comment #214 from Don Lewis <truckman@FreeBSD.org> --- I'm not familiar enough with the Linux memory map to comment, but I haven't seen any reports of hang/reboot problems that sound like what what we ran i= nto. There have been reports of idle machines having problems that seem to be resolved by avoiding the deep Cx states. I don't know if that is a potenti= al problem for us since our default seems to be: hw.acpi.cpu.cx_lowest: C1 It would be nice if the "safe area" was documented. This doesn't appear to= be an issue with Intel CPUs. My AMD FX-8320E is happy with the pre-Ryzen loca= tion of our signal trampoline code. I haven't run my test program on it because= I'm keeping it busy doing the port builds that I'd hoped to be doing on my new Ryzen box. --=20 You are receiving this mail because: You are the assignee for the bug.=
