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
