Comment 106 for bug 1007765

I fresh installed Ubuntu 13.10, so it was using free drivers by default. And it crashed when I tried to change brightness rapidly. So I think the bug is not present in fglrx-installer. Now I am using AMD drivers, but my brightness control doesn't work properly, it either increases or decreases after pressing the key many times, the progress bar in indicator is displayed correctly but brightness changes randomly.
After echo 0 >/proc/sys/kernel/nmi_watchdog, crash doesn't occur.
