I would have to know what hardware you have and see the dmesg log after the resume from hibernate. You can open a bz and assign it to me. Just attach the dmesg log, lspci and lspci -t output to the bz. Though this is most likely a pci device firmware problem. But I can try to narrow it down. Cheers, Don
