I have been using kexec successfully on rb532 w/ 2.6.24, and apart that it did mangle the serial console ouput, the kexec'd kernel booted fine, but that was prior to upgrading to kexec-tools-2.0.0. I will give it a try and report back here. -- Best regards, Florian Fainelli Email : flor...@openwrt.org http://openwrt.org -------------------------------
