Have tested the linux-image-5.11.0-33-generic:amd64 5.11.0-33.35 from proposed and I can verify it fixed the issue for me.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- hirsute' to 'verification-done-hirsute'. If the problem still exists, change the tag 'verification-needed-hirsute' to 'verification-failed- hirsute'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

[Bug 1931301] Re: NIC unavailable after suspend to RAM
> Trying to ifconfig it down/up results in: > SIOCSIFFLAGS: No such device that likely means the kernel driver had some problem waking the device back up, but there's no dmesg attached to the bug so i don't know. This is probably a bug in the 'alx' kernel driver (or, problem with the hardware), not network-manager. ** Package changed: network-manager (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1931301 Title: NIC unavailable after suspend to RAM To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1931301/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
