Description Jason Tubnor 2018-12-05 23:49:34 UTC
The em driver on my Lenovo T450 does not re-initialise after resuming from sleep.  This is on 12.0-RC3 but it has always been an issue with the 11 series too.

How-to replicate:

Have a functioning network on the em0 interface, usually getting an address via dhcp.

Put laptop to sleep for 30s

Remove patch lead from laptop

Wake laptop from sleep, re-insert patch lead after 10s and perform ping/tcpdump, no traffic will pass.

Note:  Problem doesn't exist as long as the patch lead always remains attached to the laptop and associated switch powered up.  But the replication above is a typical daily scenario for a laptop.

Below is the pciconf -lcvb and dmesg output after wake:
