Hello,
I had a NanoPi M4v2 running 5.10.63 (buster) for a while without issue. Both I2C and SPI were working perfectly fine and the system was stable. Today apt updated the kernel to 5.15.25 and it broke multiple things, the first issue was that the network wasn't working properly, yellow light but not green one / no IP requested from the local DHCP server.
The overlays on this system were:
overlays=dwc3-0-host i2c7 i2c8 spi-spidev
overlays=dwc3-0-host i2c7
