https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D205549 John Baldwin <jhb@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jhb@FreeBSD.org --- Comment #3 from John Baldwin <jhb@FreeBSD.org> --- So it sounds like Linux is doing something during a clean shutdown to "shut" the xhci device down in a way that on boot doesn't get re-enabled. What I would do perhaps is start by comparing the first 64 bytes of PCI config spa= ce of the device on the host before booting the Linux VM and after the clean shutdown of the Linux VM. You can get a copy of the config registers by do= ing 'pciconf -r ppt0 0:0x3f'. --=20 You are receiving this mail because: You are the assignee for the bug.=
