Package: bash-completion
Version: 1:2.0-1
Problem: The modules completion is performed by this function
_modules()
{
local modpath
modpath=/lib/modules/$1
COMPREPLY=( $( compgen -W "$( command ls -RL $modpath 2>/dev/null | \
sed -ne 's/^\(.*\)\.k\{0,1\}o\(\.[gx]z\)\{0,1\}$/\1/p' )" -- "$cur" ) )
}
Because the "-L" option, the command "ls" above follows symbolic links.
For this reason, the completion of the commands "modinfo" and "modprobe"
takes a really very long time when you have the symlinks "build"
and "source" in $modpath.
These symlinks are automatically added by the kernel's Debian package
generated by make-kpkg.
Fix: Just drop the "-L" option in the command "ls".
Alternatively you can use something like
find -P $modpath -type f -name '*.ko' 2>/dev/null | \
sed -e 's|.*/||g;s/[.]ko$//'

Fernando Auil
