No, the standard ISOs won’t boot due to the lack of RPI firmware, the images I posted you in that links and baked with RPI firmware, standard kernel and uboot, so it should boot fine on RPI but you won’t have RPI kernel " so some patches / features won’t be available ". This effort is aimed to have a generic image that can run on as many SoC as we can, some hardware is pretty great but they lack the enterprise linux images, and we are trying to bridge this gap. Give it a go, try installing it, then install kernel 6, I think this should work 
let me know!
Sounds interesting, what is the difference between the rk3399 and sda images you linked, and which one should I use?
the rk3399 is for rock chips “rockpro64” boards, images are the same, the rk3399 has uboot images dd-ed into them, use the generic one, https://rockyrepos.gnulab.org/images/Rocky-9.1-aarch64-generic-Minimal-sda.raw.tar.gz and make sure to check the readme
I tried using the generic one now, downloaded, verified checksum, dd’d it onto my SD card, but it wont boot successfully. I can see that it passes uboot, the logo is shown in the upper right corner, and then it looks like Rocky starts booting up, but then after a bunch of startup output the screen just goes black and I never reach the login prompt.
Well the blank screen is expected and takes a bit of time, some people did complain that sometimes the HDMI won’t get back any signal depend on your screen, wait like 1 minute, then try to unplug and replug the HDMI or SSH into the box, just ran a fresh test on RPI4 model b and it works fine. Also installed the kernel-ml from elrepo but that won’t boot, I guess there might be some patches needed like the generic LTS kernel.
Is that to say that I just need to wait for the next LTS kernel release upstream, or do you mean that the generic image you linked from gnulab needs to be patched?
Could you elaborate on the “some patches needed” part? What is needed to get kernel-ml to run?
I spoke with Pablo, and it might be just some build configurations or drivers in initramfs, I am running a test now
I had a chat with @pgreco and we guess found what modules are missing, I will have to rebuild and test before I get back to you @toracat
Thank you! Pablo is my go-to genius.

Crossing my fingers for this one
Okay, it worked no patching needed just some configurations, @toracat , I started by adding the following:
CONFIG_ARCH_BCM=y
CONFIG_ARCH_BCM2835=y
and that did lead to adding all the following " basiclly whenever I get a build error, I just add what is needed and turn n → y

@alt so what you need to do is the following:
- dd my generic R9 image from Index of /images/ without the rk3399 “it won’t matter but better not use rk3399” into and SDCARD or USBkey
- if the screen goes black and your SDcard LED off, change the HDMI port, or go headless and SSH into the machine
- Download this repo file https://rockyrepos.gnulab.org/elrepo_gnulab_ml_r9_kernel.repo" you can disable elrepo repos for now "
- SSH or keyboard/mouse to your running PI, and
dnf install kernel-ml - reboot test and see how are things, also you wlll have a grub menu

Excellent!
I’ll try to get these config changes into elrepo’s kernel.

That would be awesome! thanks and I am sure you will do way better job than me to check which can be turned into a module
Of the config options, the following are type “tristate”, so can be made =m
CONFIG_PCIE_BRCMSTB
CONFIG_SERIAL_8250_BCM2835AUX
CONFIG_I2C_BCM2835
CONFIG_SPI_BCM2835
CONFIG_SPI_BCM2835AUX
CONFIG_SPI_BCM_QSPI
CONFIG_BCM2711_THERMAL

CONFIG_DRM_V3D
CONFIG_SND_BCM2835_SOC_I2S
CONFIG_MMC_SDHCI_IPROC
CONFIG_MMC_BCM2835
CONFIG_DMA_BCM2835
These will remain =y

b*cat has been watching the topic from afar but, with t*cat’s assistance, will try to build an updated version of kernel-ml for release by the ELRepo Project.

awesome, didn’t know that elrepo has so many cats 
thanks again! would be nice to have this upstream for generic aarch64 images:)

@alt and anyone interested in elrepo’s kernel-ml that runs on R-Pi4:
There is a testing kernel-ml package set available for download from under the following directory –
https://elrepo.org/people/ajb/devel/kernel-ml/el9/
It has been given a “bcat2” tag for identification purposes (kernel-ml-6.1.0-1.bcat2.el9.elrepo).
When convenient, please test and report your observations.
