Well, I've tried the kthread freezer patch against 2.6.8-rc2-mm1 and it works fine. However, with kthread freezer applied, suspending and resuming is much slower (around 5 seconds slower). Thus, I guess all my problems must be related to some specific patch I'm applying against the current -bk tree.
I'll keep investigating this issue, but I think voluntary-preempt might have some strange interactions with these kthread changes.
