| |
Hi,
I have several NICs enslaved to a bridge.
Enabling powermanagement (setting the pcie device power/control to auto) for an intel I211 Gigabit Network device hangs the Linux kernel's netlink interface. Commands like `ip addr show` no longer work but just hang. Note: There's nothing connected to the i211, so I assume it goes to sleep indeed. There's no recovery -- trying to echo "on" to the power/control does not recover the netlink interface -- I have not found a better recovery than rebooting yet.
This problem did not exist in 5.10.y kernels, it does exist in 5.15.[01]. The device is powered by the igb driver.
Let me know if this problem is not known yet and you need more information.
Best,
