Hi, adding PCI folks. Here is the story: * Wzyboy has a Lenovo laptop with _OSC control *not* granted * L1 Active is enabled * kernel: 3.12.0 * Nic is PCIe (Gen2 but not sure...) At some random point, the driver loses access to the NIC: all readl operation return 0xff. Even lspci returns 0xff: 03:00.0 Network controller: Intel Corporation Wireless 7260 (rev ff) 00: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff 10: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff 20: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff 30: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff here is the output of lspci *before* the issue hits: 03:00.0 Network controller: Intel Corporation Wireless 7260 (rev 6b) 00: 86 80 b2 08 06 04 10 00 6b 00 80 02 10 00 00 00 10: 04 00 40 f0 00 00 00 00 00 00 00 00 00 00 00 00 20: 00 00 00 00 00 00 00 00 00 00 00 00 86 80 62 c2 30: 00 00 00 00 c8 00 00 00 00 00 00 00 09 01 00 00 have you any idea of what we can do to understand what it going wrong here?
