No, this is a Linux only system, but something else clashed. More details:
System was tested with kernel mainline 6.3.7 and 6.4.0 Reverting the patch files => Didn't helped (rmmod/modprobe and reboot) Tried original Ubuntu 6.2.0 kernel and this worked again. Removed mainline kernels and reinstalled 6.4.0 which now worked with old firmware package (20230323.gitbcdcfbcf-0ubuntu1) Reinstall new firmware package and it works now with mainline kernel 6.4.0 Second thoughts: As you can see above last working boot was 16:27:57, and this was already a boot with kernel 6.4.0 and latest firmware package 20230629 (I overlooked this one). But I remember now, I was shortly away after boot and the system was going into sleep. After wake-up the system freezed and I rebooted at 16:55:52 and after this reboot mt7921e failed. So, the issue could be the sleep mode. :-/ So, the issue can be closed.
