Kernel BUG at fs/iomap/buffered-io.c:1061

Hello everyone, I'd like to report the following bug introduced with the new kernel 7.0.*

Copying to and from a disk—in my case, from xfs to ntfs or vice versa—generates a bug. The operation is initialized, but the files aren't completely copied or moved because the operation hangs.

I don't know if this would cause data loss.

Even if you cancel the operation from the file manager, the process responsible for the transfer is not terminated and its termination must be forced even just to restart the system.

Sure it's the FS and not the disk?
