I also encountered errors with network drivers on the new kernels. I was using this [rtl88x2bu](https://github.com/cilynx/rtl88x2bu) which broke after the update. I eventually got [this one](https://github.com/RinCat/RTL88x2BU-Linux-Driver) to work, but it threw me for a loop for a while.
I've encountered bugs that broke video or network drivers. Invariably others had reported the bugs by the time I looked them up. I had to stick with an older kernel until a fix was available. With buggy video drivers the text console is usually still available to view dmesg for errors. --
