I just noticed this message. Don't know if you found an answer in the meantime.
This is almost certainly a kernel bug. pm-utils can work around some
things in userspace, but eventually it just tells the kernel to
suspend and hope it resumes in a usable state.
I would suggest trying a newer kernel version at least. Probably
advisable to open a Fedora bug. If that doesn't get you anywhere, you
can try the vanilla kernel.org kernels and contacting lkml.org,
linux-a...@kernel.org and/or kernel.org bugzilla.
Also, you may want to look at dmesg to see if there's any messages
from the acpi subsystem.
