Additional context

No response

pelwell commented 8 months ago

What hardware was attached? Neither I2c1 nor spi0 would normally be enabled and active.

mgrouch commented 8 months ago

No i2c or spi hardware is attached but kernel modules are enabled

pelwell commented 8 months ago

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 this happened? Seconds, minutes or hours?

mgrouch commented 8 months ago

Software called Pypilot is probing them. https://github.com/pypilot/pypilot

However errors start after hours of probing and running without kernel errors.

So it looks there is some kind of kernel bug in drivers.

Thanks

pelwell commented 8 months ago

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 common infrastructure has failed and taken both out.

I'll have a look at what pypilot is doing and try to do more of it.

pelwell commented 7 months ago

Possibly caused by #5865.

pelwell commented 6 months ago

Probably fixed by #6044.
