19 If you want loopback devices to "just work", they should be compiled
20 into the kernel, like so...
21
22 make menuconfig
23 Device Drivers --->
24 Block devices --->
25 <*> Loopback device support
26
27 My guess is that somewhere along the line, the "<*>" got changed to a
28 "<M>". Change it back to "<*>", recompile the kernel and any necessary
29 modules, and reboot.
