This is kinda confusing.
So the gist is that the guest OS is Windows, so the VDI contains an
NTFS file system. Correct? And that VDI is on a Btrfs formatted bcache
device. Correct? Does the VDI have +C xattr set?

Hello!
Since one of the last kernel updates (I don't know which exactly), I'm
experiencing csum errors within VDI files when running VirtualBox. A
side effect of this is, as soon as dmesg shows these errors, commands
like "du" and "df" hang until reboot.
I've now restored the file from backup but
