Title:
Ethernet interface stops working after a few seconds
Status in linux package in Ubuntu:
Invalid
Bug description:
After plugging a ethernet cable into the laptop (Dell Latitude E7440),
Network Manager picks up as expected, requests a IP address and
configures the interface. After a couple of seconds, the interface
stops working. The interface start to response to packets only after
unplugging the cable and plugging it in again; disabling and enabling
the interface does not help.
With dmesg I can see some ACPI errors everytime I plug a cable:
[ 76.322029] e1000e: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow
Control: None
[ 81.345308] ACPI Error: Index value 0x0000000000000083 overflows field
width 0x7 (20150619/exfldio-341)
[ 81.345329] ACPI Error: Method parse/execution failed [\NEVT] (Node
ffff88040e0c7258), AE_AML_REGISTER_LIMIT (20150619/psparse-536)
[ 81.345344] ACPI Error: Method parse/execution failed
[\_SB_.PCI0.LPCB.ECDV._Q66] (Node ffff88040e0c4b90), AE_AML_REGISTER_LIMIT
(20150619/psparse-536)
The 15 second gap between "Link is Up" and the ACPI error matches
nicely the max. 15 ping echoes received.
I found bug 1501993 " drivers/gpu/drm/i915/intel_display.c:12326
check_crtc_state+0x2c5/0x440 [i915]() ", which has a completely
different effect, but states exactly the same ACPI errors in comment
#35.
Tried BIOS A16, A10 and A04, also kernels 4.2.0-18-generic
(current), 4.2.0-16-generic and the vanilla 4.3.0-040300-generic, but
without any effect or changed behaviour.
