kdump on linux v3.5-rc1

Hi Folks,

I'm updating to a 3.5-rc1 based kernel and I have noticed that now kdump is no longer working. The symptom is that when I

'echo c > /proc/sysrq-trigger'

I do crash the machine, but then nothing happens... i.e. the dump kernel never kicks off. Initially I was using kdump version 0.7.8, but now I have upgaded to 0.8.1-13.1.3, building from the open suse source rpm (on sles11sp1).

Does this ring any bells for you? I'd appreciate any assistance you can provide.

Thanks,
Ben
