I opened a but for this already, but I figured I'd ask here to see if anyone's encountered it before.
I have a FreeBSD 10.3-BETA2 system with a Skylake CPU and a Z170 motherboard that stops booting when I try to use PCI passthrough. After the boot loarder runs, but before root is mounted, an interrupt storm causes controllers/devices (including the root disk) to be disconnected and reconnected. Then, the system isn't able to mount the root disk, and the boot fails. Disabling VT-d, removing vmm_load from loader.conf, and removing pptdevs from loader.conf all fix the booting issue, but those are all needed for PCI passthrough. I've reproduced this with different devices, but the report is PCI passthrough of the onboard ethernet controller. : https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=207602 _______________________________________________ firstname.lastname@example.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"
