[-- Attachment #1 --] Hello to everyone. In some FreeBSD 13.1 machines I have the problem below,in some others I don't have it. I would like to know what the causes could be and how to fix it. root@marietto:/usr/home/marietto # devctl detach pci0:1:0:0 devctl: Failed to detach pci0:1:0:0: Device busy root@marietto:/usr/home/marietto # devctl detach pci0:2:0:0 devctl: Failed to detach pci0:2:0:0: Device busy Not even it works if instead of detach them, I try to attach them directly to the ppt driver : root@marietto:/usr/home/marietto/bhyve/Files # devctl set driver pci0:2:0:0 ppt devctl: Failed to set pci0:2:0:0 driver to ppt: Device busy root@marietto:/usr/home/marietto/bhyve/Files # devctl detach pci0:2:0:0 devctl: Failed to detach pci0:2:0:0: Device busy Pci addresses 1:0:0 and 2:0:0 belong to the two GPUs that I have on my PC : vgapci0@pci0:1:0:0: class=0x030000 rev=0xa1 hdr=0x00 vendor=0x10de device=0x1c02 subvendor=0x19da subdevice=0x2438 vgapci1@pci0:2:0:0: class=0x030000 rev=0xa1 hdr=0x00 vendor=0x10de device=0x1e04 subvendor=0x19da subdevice=0x2503 Actually I have commented this line on /boot/loader.conf,because it makes no difference if I keep it uncommented or not. It is totally ignored. #pptdevs="1/0/0 1/0/1 2/0/0 2/0/1 2/0/2 2/0/3" In every FreeBSD machine I load the nvidia kernel modules adding the line below to /etc/rc.conf : kld_list="nvidia nvidia-modeset" and I have installed the nvidia-driver package on every machine. But as I said,in some of them I see the error above,in some others I don't see it. I'm not able to isolate the dysfunctional pattern. The xorg.conf file is the same for each machine. Can someone help me to troubleshoot the error ? thanks. -- Mario.
