That's not supported and will result in the filesystem getting corrupted. But in dmesg there are also issues with the FS on /dev/nvme0n1p6. If Windows indeed runs in your Funtoo as a VM, then describe how exactly do you launch the VM and what devices are passed to it (and how). Apart from not mounting one FS at the same time, could it be that the guest OS had access to other partitions as well? -- With respect, Roman
