If the system was running flawless before installing OMV and does not after I suggest to blame them 😄.
What armbian-config more or less does only is downloading the omv install script and execute it.

Slightly off-topic but interesting. Quite a while ago I tested a 16:10 monitor with 1920x1200 resolution on the Station P1 I could not get to work with other kernels than legacy 4.4.y. Which branch did you build against? current or edge?
IIRC there is some sort of Asus related package within Debian/Ubuntu repository. Maybe that will deal with your issue.
Regarding forums I do not see any further content from you. New users are limited in posting for a short period of time. This measure is unfortunately necessary in order to fight spam.
Not sure but I think there were some very recent changes about this pushed to master (?). Maybe check against trunk images? (https://github.com/armbian/build/releases/download/23.02.0-trunk.0191/Armbian_23.02.0-trunk.0191_Orangepi5_jammy_legacy_5.10.110_minimal.img.xz)
Regardless, all pre-built downloadable images from Armbian are built using the same build script as it is available on Github. Just with a bunch of - partially undocumented - switches that allow better automation and build distribution in that matter.
No reason. In this particular case however it might been the influence of the BSP.
Well there is no warranty that it gets accepted, however if it is well documented and enabled across all configurations so people/maintainer have a chance to test I don't see a reason against.
It is always handy to have multple sdcards from various vendors with different sizes laying around since there are a few boards out there that are picky about sdcards. For example I have a Nanopi R4S that refuses to boot from 64G microSD Sandisk Extreme U3 but works fine with the same model in 32G.
Anyway since it has been confirmed that the image works I assume either broken PCB, bad SD or powering issue where I guess former is the case since undervoltage should not be an issue with RPi charger that outputs slight overvoltage by default.
RPi3 compatibility seemed to got lost with the latest release. Reason unknown. Try older release. Be aware when doing do and upgrading firmware it might ran into unbootable state again. Feel free to do so anyway and report if that is the case.
