I've got this bug too. For me disabling modules didn't work. But I found out that it depends on the software which is running after resuming. I can suspend/resume from recovery-console, or from commandline only. But as soon as I try to load some gnome-related applications (nautilus, gedit, gnome-panel etc) ksoftirq goes to 100%. I've tracked this down to the udisks-daemon, which starts as soon as one of those programs is started. pkilling udisks-daemon didn't work. As a workaround I've renamed udisks-daemon (which is in /usr/lib/udisks/ )
