Date: Mon, 14 Apr 2014 11:30:33 -0400 Message-Id: <84356b1cb9452226d54641a71e4b1363e78d4417.1397260362.git.joseph.salisbury@canonical.com> X-Mailer: git-send-email 1.9.1 In-Reply-To: References: Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org BugLink: http://bugs.launchpad.net/bugs/1306677 While booting the PPC64EL kernel, the command line gets truncated to 512 characters. This is due to a hard limit of 512 defined for COMMAND_LINE_SIZE. It would be beneficial to have a command line longer than 512 characters, as iscsi targets and cloud-init parameters are passed through the kernel command line.
