Steps to reproduce: - Boot kernel with a command line longer than 256 chars - cat /proc/cmdline | wc -c - kexec-reboot - cat /proc/cmdline | wc -c -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
