Description emailgrant 2013-10-07 12:16:42 UTC 
If I set up kdump and issue 'echo c > /proc/sysrq-trigger' with an HDMI cable attached to a TV and to the Mini DisplayPort on my Dell XPS 13 laptop, the crashkernel crashes right away on at least 3.10.5 and 3.11.3.  If I disconnect the cable, the crashkernel loads fine.  I'm running Gentoo.
