That sounds unlikely;  it would mean this is a bug in Linux.  Are you sure it
was locked in that call, rather than _after_ it?

You can use gdb to determine.  Try building a debug grub-mkdevicemap
(DEB_BUILD_OPTIONS=nostrip,noopt,debug), run it with gdb and interrupt it
where it has hung, then obtain a backtrace ("bt").
