i've experienced the same/very similar issue on a crappy dlink nic (sk0 driver) that worked fine before upgrading from 2.1.x –> 2.2.x .... so in my case very similar situation with a non-intel nic. (haven't found the time to swap nics)
currently i'm rebooting the firewall every morning at 5am and haven't received any reports like "please fix my internets"
Could be the same solution for that, try disabling MSI and MSIX.
In the Intel case, it appears the new driver wants to enable things that don't work on some small minority of cards. Could be a similar cause, though completely different root problem given different hardware and driver.
Some rebranded cards, like the HP i350s, may have MSIX disabled in the firmware, but still identify as an Intel i350, which can cause issues. Nothing like saving $10 on a $140 card just to have driver issues or reduced performance because they've disabled or otherwise customized the card.
