Ubuntu 22.04.02: wired ethernet e1000e stops working after resuming from suspend

Recently installed a wired ethernet to a long running Ubuntu 22.04.02 system, and the ethernet network fails to reconnect after resuming from suspend. The wifi works fine, it's only the wired ethernet that fails. No problems after a reboot, until I suspend the next time.

It's using the e1000e driver. lspci shows

0000:00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (17) I219-LM (rev 11)
    Subsystem: Dell Ethernet Connection (17) I219-LM
    Kernel driver in use: e1000e
    Kernel modules: e1000e

and lshw -C Network shows:

       resources: irq:218 memory:75180000-7519ffff

removing and reloading the e1000e kernel module doesn't help, nor does restarting the NetworkManager service.

Any suggestions?

don't think that this is related, as there are no error messages in the logs, and it's 100% reproducible with the first suspend after a reboot.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
