LAN 2.5G link flapping after 3/6 upgrade

On March 6, 2025, at 00:49 EST, Verizon pushed an upgrade to my CR1000A:

2025 Mar 6 00:48:59 info sysup: [SYS.6][SYS] Performing system upgrade...
2025 Mar 6 00:49:49 info sysup: [SYS.6][SYS] Refreshing system...

At that time, my machine connected directly to the 10G LAN port at 2.5G started experiencing link flapping regularly, which had never happened before:

Mar 6 00:50:10 kernel: [9091088.277436] r8125: ens1: link down
Mar 6 00:50:15 kernel: [9091092.608126] r8125: ens1: link up
Mar 6 00:50:37 kernel: [9091115.240391] r8125: ens1: link down
Mar 6 00:50:43 kernel: [9091120.555607] r8125: ens1: link up
Mar 6 00:54:27 kernel: [9091344.459361] r8125: ens1: link down
Mar 6 00:54:31 kernel: [9091348.742020] r8125: ens1: link up

I tried restarting everything from the ONT inward.  I've changed the cable on that connection (cat6).  Nothing else changed around that time, so it has to be the upgrade.  Anyone else?
