Looking at hurd/libstore/part.c, I see

if (run.start % source->block_size != 0)
  err = EIO;
if (run.length % source->block_size != 0)
  err = EIO;

could it be that your partitions are not aligned on 4096 bytes?

That is not surprising: ls uses stat, and thus triggers the start of
each and every translator in /dev. It should be able to terminate,
though, it could be useful to try

for i in /dev/* ; do echo $i ; ls $i ; done

to see which one apparently hangs.
