Kernel (or to be specific, gentoo-sources) version currently marked as stable (at least on x86 and amd64) contain updates to loopback-device code which dynamically handles creation and destruction of /dev/loopX devices (see http://lkml.org/lkml/2011/7/26/148). In order for this to be handled by userspace, util-linux version at least 2.21 is required. However, the latest version marked stable (at least on amd64, anyway) is 2.20.1. This makes it impossible to use loopback devices unless Reproducible: Always Steps to Reproduce: 1. Obtain a file containing a file system, e.g. an ISO image 2. modprobe loop (if necessary) 3. mount /path/to/file /mountpoint -o loop Actual Results: Error message: mount: Could not find any loop device. Maybe this kernel does not know about the loop device? (If so, recompile or `modprobe loop'.) Expected Results: Specified file is mounted as a loopback device. The problem can be worked around by restoring legacy behaviour of creating /dev/loopX files when the loop module is loaded, by passing the module the max_loop=N option (where N is the number of loop devices to be created).
I don't see an issue with getting this stabled based on the existing bugs.
