There are quite some linux kernel issues with Odroid N2 and USB, there are even issues with home assistant OS after kernel upgrades. Im not technical enough to find the solution so i just hope "someone" does somewhere on the interwebs, in the meantime i run older kernels 😏

Tested out a few kernels and 5.15.93 seems to be one of the later that's still working. No USB 3 ports work with my USB stick whith recent kernels (it's not just the OTG port that is broken).

I changed this in the dt and got more than double the speeds from my Samsung U3 SD card: However I have no idea what the process of getting this into the kernel source looks like. --- rk3399-rock-pi-4b.dts 2023-10-04 15:36:05.031221270 +0200 +++ rk3399-rock-pi-4b-mod.dts 2023-10-04 00:34:15.773888431 +0200 @@ -342,6 +342,7 @@ disable-wp; pinctrl-names = "default"; pinctrl-0 = <0x26 0x27 0x28 0x29>; + sd-uhs-sdr104; phandle = <0xce>; };

I also got problems with my HC4 when running some of the latest kernels: 1) LVM would not start correctly on my cached devices (however if i dont mount them at boot i could get them to work, can have something to do with root partition on LVM) 2) I could not get cgroups to work in my k3s cluster 3) reboot command causes a shutdown (however this is not verified it is the kernels fault, could be the SD card according to this forum, but it has worked before) I don't have much more info as i quickly downgraded to 22.08.1 / Kernel 5.19.5 again to get my cluster running, and cant really remember what kernels I tried. But two of the "more later" kernels had these issues. To be fair it was not my meaning to upgrade the kernel as the HC4 have had some kernel issues historically, I had frozen kernel updates but must have accidentally un-frozen them. This is just a F.Y.I my fileserver node is running fine now and I'm not in a need to update to debian 12.

No problems here and I reboot pretty frequently, now running 6.1.11. Using a 2Tb 3.5 inch HDD and a 256mb SSD. Could it be unrelated to system upgrades and just be dodgy hardware that is likely to break at boot when there is a power surge? Anyway good to know about the power regulator. Edit: Now found the other threads that makes it seem like a kernel issue. Anyway I'm using pretty old drives on my HC4, and it is also a quite old HC4 that I bought just after it was announced.
