This has been solved in my case, details in last post in thread.
So, I've been working on migrating to 5.28, but I've run across an issue. If I'm watching flash video for very long, X crashes. In 5.25, after an X crash, a simple xwin restarts it. But it refuses to restart without a reboot. Even attempting to reconfigure with xorgwizard and restarting fails if I do not reboot. After rebooting, alsa fails. Attempting to reconfigure alsa with alsawizard fails.

Again, it doesn't happen this way in 5.25. When they crash while playing Flash Video, I can restart X or reboot and alsa is fine. Besides, it crashes much more rarely, several hours of flash video at a minimum.
So, did alsa change between 5.25 and 5.28? Is there any log or other useful info I could post for people who care to look at?
