Any hints what I might try except for bisecting? Well, this most likely is a result of the recent PCI PM core changes, but it's hard to say which of them exactly is responsible in this particular case. Please open a bug at bugzilla.kernel.org with a CC to me and put your system information in there (the output of 'lspci -vv', /proc/iomem, /proc/interrupts, boot log). Also please try to reproduce the problem in the minimal configuration (init=/bin/bash, /proc and /sys mounted manually).
