So there should have been nothing accessing the I2C an SPI busses, unless some software is probing them. Any thoughts? Roughly how long had the Pi 5 been up when...

It's very suspicious that both fail at the same time - either one has failed and taken down the other (perhaps by failing to acknowledge an interrupt etc.), or some...

Possibly caused by #5865.

Probably fixed by #6044.

This area is for problems with the Raspberry Pi Linux kernel. We don't provide support for Kali Linux, its apps and packages. If you identify a problem with our Linux...

It seems to me that the RX DMA code in the PL011 driver is incompatible with break handling. The break indication is carried with the error flags in the top...

Yes, that's the non-DMA code that reads the full 12-bit values and looks at the flags. The DMA path just reads the lower 8 bits.

This behaviour is by design. The Pi 4 performs better with a 64-bit kernel, so it is chosen by default.

Other distros are free to add `arm64bit=0` if they prefer.

A 64-bit kernel can host a 32-bit OS, but a 32-bit kernel can't host a 64-bit OS - the CPU architecture just doesn't allow it. For that reason, our 64-bit...
