Kernel Bond Debugging in RHEL CoreOS

Fri, 02/14/2025 - 21:56 by bnemec

I'm working on a bug that involves functionality at a fairly low level, at least much lower than I usually deal with. One request from the experts who are helping me with this was to enable kernel bond debugging, which is not something I've ever done. At runtime this isn't too difficult, just two commands:

sysctl -w kernel.printk=8
echo 'module bonding +p' > /sys/kernel/debug/dynamic_debug/control
