Radeon kernel driver: Debugging

[xeno74]

First:

setenv bootargs root=<root_partition> modprobe.blacklist=radeon (this will prevent the radeon kernel driver from getting loaded automatically).

Then once the system is booted up, log in via SSH and run

sudo modprobe radeon

This way you should be able to capture dmesg output from loading the radeon driver.

Please note: You need the radeon kernel driver as a module.

The radeon graphics driver is part of our kernel and cannot be blacklisted via modprobe. Use the initcall_blacklist kernel parameter instead.

Code: Select all

initcall_blacklist=radeon_init
