https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=290997 --- Comment #13 from Corvin Köhne <corvink@FreeBSD.org> --- (In reply to Nils Beyer from comment #12) As mentioned earlier resizable BARs are not supported, so you should disable them in your Host BIOS. Additionally, it would be worth trying to pass the GPU ROM to the guest. Therefore, you have to extract it on a Linux or Windows system, e.g. http://etherboot.org/wiki/romdumping, and then make use of the rom parameter from passthru. -- You are receiving this mail because: You are the assignee for the bug.
