I can't get my machine to boot into anything usable with that configuration. I'm running ubuntu so its starting right into X and sometime between showing the available users and me clicking the icon to login the machine freezes. I can see in the system tray that the wifi adapter is being activated and appears to have associated with an AP, I just can't do much beyond that as the keyboard backlight wakes up, but the caps lock key doesn't work. I see similar behavior with the 5.9 configuration, but after a reboot or two I win whatever race is occuring. With 5.10, I tried maybe 10-15 times with 0 success.
