Howdy, On a thinkpad T540p (but I could swear I had this on my T530 too), if I unplug the ethernet cable I was using, NM switches back to wireless and all is good, except that my logs get heavily spammed with:
e1000e 0000:00:19.0 eth0: Detected Hardware Unit Hang: TDH <0> TDT <4> next_to_use <4> next_to_clean <0> buffer_info[next_to_clean]: time_stamp <10016edb7> next_to_watch <0> jiffies <100174da5> next_to_watch.status <0> MAC Status <80080> PHY Status <7949> PHY 1000BASE-T Status <0> PHY Extended Status <3000> PCI Status <10> I get one log entry every 2 seconds forever (or until I unload e1000e) I have 00:19.0 Ethernet controller: Intel Corporation Device 153a (rev 04) Kernel: 3.12.7 Boot says: e1000e: Intel(R) PRO/1000 Network Driver - 2.3.2-k e1000e: Copyright(c) 1999 - 2013 Intel Corporation. e1000e 0000:00:19.0: setting latency timer to 64 e1000e 0000:00:19.0: Interrupt Throttling Rate (ints/sec) set to dynamic conservative mode e1000e 0000:00:19.0: irq 48 for MSI/MSI-X rmmod e1000e makes this go away, but the interface does not seem to work after I do modprobe e1000e (dhcp never completes, and tcpdump -n -i eth0 shown no inbound traffic) At that point, fix seems to be a reboot. Scratch that, going to S3 sleep and waking up seems to fix it too. Last, but not least, before my last reboot when eth0 was wedged, I was seeing this: kernel: [231510.362713] e1000e 0000:00:19.0 eth0: Error reading PHY register kernel: [231511.162238] e1000e 0000:00:19.0 eth0: Error reading PHY register kernel: [231511.961733] e1000e 0000:00:19.0 eth0: Error reading PHY register kernel: [231512.761187] e1000e 0000:00:19.0 eth0: Error reading PHY register kernel: [231513.560625] e1000e 0000:00:19.0 eth0: Error reading PHY register kernel: [231514.360756] e1000e 0000:00:19.0 eth0: Error reading PHY register kernel: [231515.160201] e1000e 0000:00:19.0 eth0: Error reading PHY register kernel: [231515.959637] e1000e 0000:00:19.0 eth0: Error reading PHY register laptop-mode: Switched auto-negotiation to on for eth0 laptop-mode: Cannot advertise speed 1000 laptop-mode: Restored speed to 1000 Mbit for eth0 Any ideas?
