Do you run into the same problem if you suspend to RAM rather then
hibernate?

No need - an ext3 file system is an ext2 file system with journaling
added. You may be able to use the -j option of tune2fs to add it
back in.

Just a WAG, but it sounds like WOL is not being enabled for the NIC
on shutdown, and is hanging the system. But I have not looked into
the settings that control this, so I leave this to someone that has
played with it...
