this makes me curious. how do you test this? dmesg > dmesg-before <upgrade and reboot> dmesg > dmesg-after

diff dmesg-* ? or is there a better way? what's the recommended approach too see "what's new" ?

I usually do "dmesg -c" which clears the ring buffer, and then start testing whatever I'm testing, and now dmesg will show only the new stuff. -- damjan
