Looks like linux-image-edge-sunxi64 didn't help. I managed to cook a custom image using u-boot and sun50i-h5-orangepi-pc2.dtb from Armbian to boot Debian's netinstaller and go from there. I'm now running Debian 12 on kernel 6.1.123-1. I'm going to let that system run for a few days and if I don't see any crash I'll probably use that as base image for the other fielded systems.

In case anyone's still interested in this, here's the diff between an up-to-date -current-sunxi64 setup and the dtb linked above: # diff sun50i-h5-orangepi-pc2.dts sun50i-h5-orangepi-pc2-armbian-forum.dts 61a62,69 > scpi { > compatible = "arm,scpi"; > mboxes = < 0x06 0x02 0x06 0x03 >; > mbox-names = "tx\0rx"; > shmem = < 0x07 >; > phandle = < 0x49 >; > }; > 65c73 < phandle = < 0x49 >; --- > phandle = < 0x4a >; 68c76 < sound-dai = < 0x06 >; --- > sound-dai = < 0x08 >; 72c80 < sound-dai = < 0x07 >; --- > sound-dai = < 0x09 >; 76,83d83 < scpi { < compatible = "arm,scpi"; < mboxes = < 0x08 0x02 0x08 0x03 >; < mbox-names = "tx\0rx"; < shmem = < 0x09 >; < phandle = < 0x4a >; < }; < 343c343 < phandle = < 0x08 >; --- > phandle = < 0x06 >; 382,383d381 < phys = < 0x18 0x00 >; < phy-names = "usb"; 394,395d391 < phys = < 0x18 0x00 >; < phy-names = "usb"; 835c831 < phandle = < 0x07 >; --- > phandle = < 0x09 >; 863c859 < dma-names = "tx\0rx"; --- > dma-names = "rx\0tx"; 879c875 < dma-names = "tx\0rx"; --- > dma-names = "rx\0tx"; 895c891 < dma-names = "tx\0rx"; --- > dma-names = "rx\0tx"; 911c907 < dma-names = "tx\0rx"; --- > dma-names = "rx\0tx"; 993c989 < phandle = < 0x06 >; --- > phandle = < 0x08 >; 1099c1095 < silergy,fixed-microvolt = < 0x10c8e0 >; --- > silergy,fixed-microvolt = < 0x124f80 >; 1191c1187 < phandle = < 0x09 >; --- > phandle = < 0x07 >; 1522a1519,1524 > > opp-1440000000 { > opp-hz = < 0x00 0x55d4a800 >; > opp-microvolt = < 0x155cc0 0x155cc0 0x155cc0 >; > clock-latency-ns = < 0x3b9b0 >; > }; 1566c1568 < linux,code = < 0x100 >; --- > linux,code = < 0x74 >; 1598d1599 < sound_hdmi = "/sound_hdmi"; 1599a1601 > sound_hdmi = "/sound_hdmi"; Unfortunately that doesn't make my systems stable (running 6.6.75-current-sunxi64): they keep kernel oopsing every few hours/days. I initially thought those crashes were related to DVFS, but even running echo 480000 >/sys/devices/system/cpu/cpufreq/policy0/scaling_max_freq to keep it at the minimum supported frequency doesn't seem to improve things. Attached is a dmesg log of a few kernel stacktraces happening right after boot. Those keep happening every few minutes until the board resets on a kernel OOPS. I'm going to give linux-image-edge-sunxi64 a shot and will report back. dmesg.log
