I've tried a couple of the later linux kernels in the 5.10.x range, and
now 5.11.0 on this domU, and get "BUG: kernel NULL pointer dereference,
address: 0000000000000000". Below is the entire console log from the
domU. Anybody know what I should do with this? Currently downgraded the
domU to linux-5.4.98, dom0 seems happy on all the available kernels from
gentoo (gentoo-sources) from 4.x to 5.11.0.
Should also note that I use some unsavory pci-passthrough practices to
give each of two domUs their own USB-adapter.

now 5.11.0 on this domU, and get "BUG: kernel NULL pointer dereference,
address: 0000000000000000". Below is the entire console log from the
domU. Anybody know what I should do with this? Currently downgraded the
domU to linux-5.4.98, dom0 seems happy on all the available kernels from
gentoo (gentoo-sources) from 4.x to 5.11.0.
Should also note that I use some unsavory pci-passthrough practices to
give each of two domUs their own USB-adapter.
