Hi everyone,

I compiled Linux 5.13.0 and use it on my Ubuntu. I got a kernel warning
at kernel/sched/fair.c:3306.

Below is the system information
Kernel: 5.13.0-icetea001-12377-gf55966571d5e
OS: Ubuntu 21.04
CPU: 4 Core
Hardware name: Acer Aspire ES1-421/OLVIA_BE, BIOS V1.05 07/02/2015

Reproduction steps:
1. Connect to a wireless (internet).
2. After several moment (the time to reproduce is random), the internet
will suddenly hang for a few seconds. After that the network is down,
but the interface state is still connected.

The only way to get the network back is reconnect the wireless.
  # Ok, after hang, internet won't work.

  # See, it's still connected.
  nmcli c

  # Disconnect
  nmcli c down qwerty;

  # Connect again
  nmcli c up qwerty;

  # Internet work again after reconnect.

3. Check `dmesg -Sr`.

Here is the warning (I attached more log and kernel config as well):
