Hello,
Many thanks for your response!

And I've tried a few more kernels now, compiled on my own. 3.17 still has this issue, 3.10 is completely fine all the way up to 3.10.57 (I've tested just under 50 cycles last night). 3.11 I tried but it seems to have other suspend-resume stability issues not present anymore in later kernels, I've mostly not used those results.
git bisect: I've finally succeeded! I've tried automating it completely, but sadly Gigabyte couldn't be bothered wiring up the motherboard to make the watchdog work. :-(
The culprit appears to be this one: 2e8b5f621dbe29425906852c6079afb6b28720cb

Merge branch 'pci/misc' into next
* pci/misc: PCI: Remove pcie_cap_has_devctl() PCI: Support PCIe Capability Slot registers only for ports with slots PCI: Remove PCIe Capability version checks PCI: Allow PCIe Capability link-related register access for switches PCI: Add offsets of PCIe capability registers PCI: Tidy bitmasks and spacing of PCIe capability definitions PCI: Remove obsolete comment reference to pci_pcie_cap2() PCI: Clarify PCI_EXP_TYPE_PCI_BRIDGE comment PCI: Rename PCIe capability definitions to follow convention PCI: Disable decoding for BAR sizing only when it was actually enabled PCI: Add comment about needing pci_msi_off() even when CONFIG_PCI_MSI=n PCI: Add pcibios_pm_ops for optional arch-specific hibernate functionality
I've then tried to narrow down which of the merged changes is my issue but with no luck, possibly because there's a problem with a combination of one of these changes, and a change that was not in the pci/misc branch at the time. I could do a manual test instead.

I can try this again with an even more minimal set. If this improves the situation, I'll post again.
