Hi all, I'm using vanilla kernels on a gentoo-based laptop and since 6.3.2 I'm getting the kernel log below when using kvm VM on my box. I know, kernel is tainted but avoiding to load nvidia driver could make things complicated on my side; if needed for debug I can try to avoid it. Not sure which other infos can be relevant in this context; if you need more details just let me know, happy to provide them.
