Comment 31 for bug 217846

Another confirmation for networks. In my case, both suspend and hibernate were extra slow.

I had to remove "auto eth1" - my wireless - from /etc/network/interfaces and it was fixed immediately.

Best guess as to why my wireless and not everyone else's is because I'm using ndiswrapper for a Broadcom card. It has a lot of quirks (which this must just be another), but otherwise works well.
