Bisected to: commit 26f41062f28de65e11d3cf353e52d0be73442be1 Author: Kay, Allen M <allen.m.kay@xxxxxxxxx> Date: Thu Jan 26 10:25:53 2012 -0800 PCI: check for pci bar restore completion and retry On some OEM systems, pci_restore_state() is called while FLR has not yet completed. As a result, PCI BAR register restore is not successful. This fix reads back the restored value and compares it with saved value and re-tries 10 times before giving up. I will try to update the BIOS on this laptop next week, hoping that it might fix some of the s2ram issues, but other than that, maybe somebody has an idea?
