Running Hardy x64 on a Mac Pro ("early 2008" model, ATI graphics card).
Hibernate (suspend-to-disk) used to work with kernel 2.6.24.16, then stopped working after an upgrade to 2.6.24.18 with the exact same symptoms.
Just enabled hardy-proposed repo, run the upgrade to 8.04.1, which also installed 2.6.24.19 kernel: hibernate works again.
