Comment 50 for bug 748994

Works for me too on a Dell Studio 1749.

Steps:

1. Create new file /etc/modprobe.d/blacklist-suspend.conf with the following two lines:

blacklist firewire_core
blacklist firewire_ohci

2. Run: sudo update-initramfs -u

3. Reboot and check that the modules were not loaded by running: lsmod | grep firewire

4. Suspend the machine and bring it back up.

5. Hibernate the machine and bring it back up.

Both suspend and hibernate work now.
