The new patch removed the annoying "bad Vcc request" messages, but that's all it improved. With the new patch I still lose cbb1 and anything connected to it. I see no real difference in the log other than the disappearance of the Vcc messages, but that is a good thing. If I set debug.suspend_power to '0', everything works as it did before. All PCI and CardBus devices seem to work fine after resume. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
