Looks like problem of missing network interface. Full log of that booting attached.

v5.13-generic boot log (proper with network device qede):
qede 01:00.00: Storm FW 8.42.2.0, Management FW 8.35.1.0 [MBI 8.35.1] [eth1]

[Joseph Salisbury (jsalisbury)]

The linux-modules-extra package is not a dependency for this kernel, which prevented installation of the qede module.

I'll submit a patch to add extra as a dependency.
