Like the title says, it appears to me that genkernel doesn't know how to handle a "new" virtio option and so just aborts. I put "new" in quotes because this has actually been an issue for a while. I've been working around it using menuconfig, but got sufficiently annoyed to post to verify whether it's a bug, and if it seems so, submit a report.

Code:

The kernel is gentoo-sources-4.4.26, no USE flags enabled. Genkernel version is 3.4.52.4-r2. This has been a thing in significantly older versions of both, though.

If I am interpreting the log correctly (and I may not be), configuration generation is hitting the "VIRTIO_PCI_LEGACY" option, which it doesn't know about, and elects to just give up. Compiling works fine without --virtio. Likewise, it errors out in the same way with and without --clean and --mrproper.

So am I missing something?
