I've had such backtraces with no other info in my log... Previous versions did not have the info, but with this patch I get: WARNING: at drivers/pci/pci-driver.c:374 pci_legacy_suspend+0x9b/0xde() Hardware name: HP Compaq 2510p Notebook PC PCI PM: Device state not saved by iwl_pci_suspend+0x0/0x4c [iwlagn] [...] Driver and function causing the warning are in the last line.
