Title:
NIC unavailable after suspend to RAM
Status in linux package in Ubuntu:
Confirmed
Bug description:
Upgraded to 21.04 (hirsute) and now the network card is unavailable
after suspend to RAM (sleep state S3). It worked flawlessly up until
20.10. My workaround for now is unloading and reloading the kernel
module, but that won't work for normal users, hence this report.
NIC in its unavailable state:
2: enp4s0: <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN group default
qlen 1000
link/ether d0:50:99:27:02:11 brd ff:ff:ff:ff:ff:ff
NIC (from lspci):
04:00.0 Ethernet controller: Qualcomm Atheros Killer E220x Gigabit Ethernet
Controller (rev 10)
Trying to ifconfig it down/up results in:
SIOCSIFFLAGS: No such device
journalctl shows (right after recovering from suspend):
NetworkManager[1911]: <info> [1623181236.9371] manager: sleep: wake
requested (sleeping: yes enabled: yes)
NetworkManager[1911]: <info> [1623181236.9372] device (enp4s0): state
change: unmanaged -> unavailable (reason 'managed', sys-iface-state: 'external')
NetworkManager[1911]: <info> [1623181236.9382] manager: NetworkManager
state is now CONNECTED_LOCAL
