Hello!
The crash only occurs if you use quota and IDE without barrier support.
The Problem is, that on a new mount of a root filesystem - the flag
VFS_RDONLY is set - and so no barrier check is done before checking
quota. With this patch barrier check is done always. The partition
should not be mounted at that moment. For mount -o remount, rw or
something like this it uses another function where VFS_RDONLY is checked.
