this is not expected.
could you list/home/dhowells/.lkp/cache

looks something wrong at below function
lizhijian@...well-OptiPlex-9020:~/lkp-tests$ vim lkp-exec/qemu +230
230 create_lkp_src_initrd()
231 {
232         if [[ "$kconfig" =~ ^(i386|x86_64)- ]]; then
233                 local arch=${kconfig%%-*}
234         else
235                 local arch=$(arch)
236         fi
237
238         if [ -d $LKP_SRC/.git ]; then
239                 local head_commit=$(cd $LKP_SRC && git rev-list -n1 HEAD)
240                 local diff_id=$(cd $LKP_SRC && git diff | git patch-id | cut -f1 -d' ')
241                 local src_sig=${head_commit:0:12}_${diff_id:0:12}
242         else
243                 local src_sig=$(ls -lR $LKP_SRC|md5sum|cut -c1-12)
244         fi
245         lkp_initrd=$CACHE_DIR/lkp-$arch-$src_sig.cgz
246         [[ -f $lkp_initrd ]] || {
247                 LKP_USER=$user \
248                 $LKP_SRC/sbin/pack -f -a $arch lkp-src
249                 mv $CACHE_DIR/lkp-$arch.cgz $lkp_initrd
250         }
251 }
