Hi Josep,

I had the exact same issue, when running dpkg it took half an hour or
so.. after chatting on IRC to Kent Overstreet I was told this was fixed,
so you might need to patch the kernel with the latest changes. I haven't
seen this issue since, but haven't done a lot of testing since either..

Cheers, Huub
