Hi everyone, thanks for all the amazing advice in this thread, I've been happily running this build for a few years now, trouble free.
After reading several posts describing the Monterey upgrade as smooth, I decided to give it a go last night. I upgraded my Big Sur to OpenCore 0.7.4, which worked great. Then I did the Monterey install, which proceeded smoothly, but after the install finished, on first boot I had a sudden hard reboot during the progress bar. This happened repeatedly, I couldn't get to the login screen. After a little more reading I noticed that the 2.5GbE NIC is reported as "not working" after install, so I unplugged the LAN from it and rebooted. This time I made it to the login screen, but had another hard reboot shortly after login. After booting up again, I made it into sysprefs and disabled the 2.5GbE NIC, and since then the system has been running happily. As reported by others, the 1GbE NIC seems to work fine. As a test, I later tried re-enabling the 2.5GbE NIC, and shortly after plugging in the LAN cable I had a hard reboot, so it seems like they're related. I wanted to mention in case it helps someone else, in at least some cases the 2.5GbE NIC might be responsible for reboots or crashes.
Thanks again for all the hard work that goes into the many updates and tireless problem solving
