Rawhide already has kernel 5.5:

pif# uname -a
Linux pif.optonline.net 5.5.0-0.rc6.git2.1.fc32.aarch64 #1 SMP Wed Jan 15 20:23:38 UTC 2020 aarch64 aarch64 aarch64 GNU/Linux

I have very close to the full 4 GB of ram available.  According to dmesg, 256K of ram is not available - it might be assigned to the video core:

Memory: 3833660K/4096000K available (12924K kernel code, 5450K rwdata, 6272K rodata, 6272K init, 26849K bss, 229572K reserved, 32768K cma-reserved)

Thx for checking Steve. That is pretty good news. afaik rawhide is now the only aarch64 distro on rpi64 (although that might change quickly now with 5.5).

This are good news Fred. :)

Maybe in a few days i can use my PI4 with 4GB and the Server Version as a FreeIPA Server :)
