Do you need me to collect all the dumps for 2.6.39-1-686.. ?

vermagic: 2.6.39-1-686-pae SMP mod_unload modversions 686
parm: pciehp_detect_mode:Slot detection mode: pcie, acpi, auto
pcie - Use PCIe based slot detection
acpi - Use ACPI for slot detection
auto(default) - Auto select mode. Use acpi option if duplicate
slot ids are found. Otherwise, use pcie option
parm: pciehp_debug:Debugging mode enabled or not (bool)
parm: pciehp_poll_mode:Using polling mechanism for hot-plug events or not (bool)
parm: pciehp_poll_time:Polling mechanism frequency, in seconds (int)
parm: pciehp_force:Force pciehp, even if OSHP is missing (bool)
Maybe I need to play around with the pciehp_detect-mode parameter?
