Linux 5.13.0-1012-raspi #14-Ubuntu SMP PREEMPT Mon Dec 6 15:27:57 UTC 2021 aarch64
Installed latest V6 nightly (10-dec-21) on a Raspberry CM4 with 8GB and with Ubuntu 64 and running from a fast Pcie SSD.
everything worked fine (schematic) but when I load the PCB it takes 15 minutes!!!
But after everything seems to work!
Did the same some 6 weeks ago with another CM4 but V5.99 (forgot the version) and there was no problem with that, tested with the same design.
Did anybody experienced the same?
I use a RPI/CM4 in order to run the latest version because it won’t install on older macs OSX like High Sierra and this because my 17" MBP is still running fine and easy to take with when I do some work outside, new macs are too small for my old eyes (but that is my problem I know 
).
