After upgrade kernel 3.19.8-100.fc20.i686 -> kernel-4.0.5-200.fc21.i686 the module atl1c fails to detect my ethernet controller. It produces the following error message: Jun 23 10:58:38 node2 kernel: [ 1.397542] atl1c 0000:02:00.0: MAC state machine can't be idle since disabled for 10ms second Jun 23 10:58:38 node2 kernel: [ 1.397624] atl1c: probe of 0000:02:00.0 failed with error -5 Additional info: 02:00.0 Ethernet controller: Qualcomm Atheros AR8151 v2.0 Gigabit Ethernet (rev c0) Subsystem: Gigabyte Technology Co., Ltd Device e000 Flags: bus master, fast devsel, latency 0, IRQ 28 Memory at f7c00000 (64-bit, non-prefetchable) [size=256K] I/O ports at e000 [size=128] Capabilities: [40] Power Management version 3 Capabilities: [48] MSI: Enable+ Count=1/1 Maskable- 64bit+ Capabilities: [58] Express Endpoint, MSI 00 Capabilities: [6c] Vital Product Data Capabilities: [100] Advanced Error Reporting Capabilities: [180] Device Serial Number ff-ce-fb-f0-50-e5-49-ff -- Alexander. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
