Re: LKCD in mainstream release?

[Simon Falvey <simon.falvey@xxxxxxxxxxx>]

Richard,

I have been sent an e-mail from a fellow IBMer of yours from India 
letting me know that a "test" release of the patch sent out to the 
mailling list actually contains ALT+SYSRQ+c key sequence which will 
invoke a crash dump. I presume that this will make it into the download 
area at some point for general consumption.

Cheers

Simon
