Wait for a few hours and see if it appears. My other theory, is that I removed the BCMHD DKMS driver and now the wifi is in a wrong state and hassling the CPU.

It is not that one. The 2.0 load was just cosmetic, the CPU was actually idle. But with this one it is actually doing something, which is also increasing heat (if no fan). With the expanded core list, you can see the CPU5 and CPU7 have "system" load of 49% and 36%. On a fully idle system. Interrupts file attached. It seems pretty normal to me. interrupts

And the CPU load bug is still not fixed even in 6.18, amazing. After the system has been up for a while, these crop up in "top", consuming quite a bit of CPU for no discernible reason. The system is otherwise idle and there's nothing running. I stopped qbittorrent and samba, this strange load does not disappear. And it seems to increase over time, a bit after the screenshot, around 30-60% now.

armbianmonitor picks up the wrong temperature to show as "Tcpu". 19:40:09 1600/1600 MHz 0.63 12% 0% 12% 0% 0% 0% 34.9 °C 0/1 19:40:14 1600/1600 MHz 0.66 12% 0% 12% 0% 0% 0% 34.9 °C 0/1 19:40:19 614/ 614 MHz 0.60 5% 0% 4% 0% 0% 0% 34.9 °C 0/1 19:40:24 614/ 614 MHz 0.56 0% 0% 0% 0% 0% 0% 34.9 °C 0/1 19:40:29 614/ 614 MHz 0.51 0% 0% 0% 0% 0% 0% 34.9 °C 0/1 19:40:34 614/ 614 MHz 0.55 1% 0% 0% 0% 0% 0% 34.9 °C 0/1 19:40:39 1000/1000 MHz 0.51 3% 1% 1% 0% 0% 0% 34.9 °C 0/1 19:40:44 614/ 614 MHz 0.47 0% 0% 0% 0% 0% 0% 34.9 °C 0/1 Time CPU_cl0/CPU_cl1 load %cpu %sys %usr %nice %io %irq Tcpu C.St. 19:40:49 1600/1600 MHz 0.51 12% 3% 8% 0% 0% 0% 34.9 °C 0/1 19:40:54 1600/1600 MHz 0.55 15% 4% 10% 0% 0% 0% 34.9 °C 0/1 19:41:00 1600/1600 MHz 0.58 15% 4% 10% 0% 0% 0% 34.9 °C 0/1 19:41:05 1600/1600 MHz 0.70 15% 4% 10% 0% 0% 0% 34.9 °C 0/1^C Meanwhile in 'sensors': cluster1_thermal-virtual-0 Adapter: Virtual device temp1: +45.0°C nvme-pci-10100 Adapter: PCI adapter Composite: +34.9°C (low = -40.1°C, high = +119.8°C) (crit = +129.8°C) Sensor 1: +42.9°C (low = -40.1°C, high = +139.8°C) Sensor 2: +34.9°C (low = -40.1°C, high = +119.8°C) cluster0_thermal-virtual-0 Adapter: Virtual device temp1: +45.0°C So it shows the NVMe SSD temperature instead.

Tried "Armbian_22.08.0-trunk_Nezha_sid_current_5.19.0_xfce_desktop.img.xz", the result there is much better, 49 MB/sec. But the WiFi onboard of LicheeRV Dock is not detected.

balbes150, There is something wrong with performance. I am trying "Armbian_23.09_Nezha_sid_current_6.1.0_xfce_desktop.img.xz" Doing my simplest performance test: dd if=/dev/zero bs=1M count=256 | md5sum The result is 21 MB/sec. Moving windows in Xfce is really sluggish, even after disabling compositor, leaves trail on screen and lags behind mouse movement. Compared to "licheerv-debian-clean-hdmi.zst" from https://linux-sunxi.org/Sipeed_Lichee_RV#Pre-made_images (last in the list). Using kernel 5.18. The same benchmark returns 51 MB/sec. Moving windows is very responsive.
