Kernel panic caused by bcm2835_spi_interupt #228

Open wbb12 opened 2 years ago

wbb12 commented 2 years ago

When I use the Raspberry Pi 4B with raspberry pi OS 64 bits, the bcm2835_spi_interupt always causes the kernel to panic. Two SPIs are used on the Pi, spi0 for mcp2515 and spi6 for ADS1263. In the beginning, two SPI devices work correctly, but the kernel panic always occurs after several minutes or several minutes. Actually, I installed the ubuntu server 22.04 64bits on another Pi and it shows the same problem.

These are the messages show on the monitor. 832c42655c8b6a5686edd3737b4ff29 a57716dddea1f995e77d08c909a718e

Both the ubuntu and raspberry pi OS are 5.15 kernel.

The SPIs devices are working well on the Pi with 32bits OS.

This is clearly a kernel bug, rather than an OS-level bug, so should probably be reported at https://github.com/raspberrypi/linux instead?

Thank you! I will report it to https://github.com/raspberrypi/linux.
