Title:
Intel PRO/1000 network driver e1000e doesn't always regain connection
Status in linux package in Ubuntu:
Triaged
Bug description:
On our Dell E6440 laptops we found that the Wired network connection
is sometimes not re-established when going from Wifi back to Ethernet,
e.g. when booting without LAN and then putting the laptop back in its
dock.
The following upstream patch resolved this problem for us in Kubuntu
14.04 LTS kernels 3.13.0-34-generic and 3.13.0-40-generic:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/patch/drivers/net/ethernet/intel/e1000e?id=b20a774495671f037e7160ea2ce8789af6b61533
Please incorporate this patch in the Kubuntu kernel so that the
/lib/modules/3.13.0-XX-
generic/kernel/drivers/net/ethernet/intel/e1000e/e1000e.ko module
doesn't have to rebuilt manually every time we follow a kernel update.
Thanks.
