I am using FreeBSD 12.2 (x64) on a desktop system, with an i9-7940X process= or, ASUS TUF X299 board, and Nvidia GTX 970 GPU. The GPU is using the nvidi= a-driver port with ACPI support, and a generic kernel. If I just ignore the computer for a while, apart from observing what it doe= s, the screen turns off after 10 minutes (as I requested). After another 10= minutes, the screen turns back on briefly, with a notification that the sy= stem is about to suspend. However, there is a little hard drive activity fo= r another five minutes or so before this activity is extinguished. At that = point the power light remains on steadily (should be blinking, as it does w= hen Windows or Linux is suspended on the same hardware). The computer canno= t be resumed with the keyboard, mouse, or power switch, and a hard reset is= needed. (The mouse is wireless, but it awakens the other two types of OS.) Since this is a desktop system, it would be acceptable to use it without po= wer management, although such efforts have been met with "panic: running wi= thout device atpic requires local APIC." Or if it is going to suspend impro= perly, it should happen after the computer has been idle for about an hour,= so that it never does actually suspend. It is possible that my hardware is= just not fully compatible with FreeBSD, but if it is I'd like to solve the= problem.=C2=A0 =C2=A0
