I enabled the magic sysrq and verified that I can use it when the system
is up and running. When provoked a resume failure, the system did not
react to any of the sysrq combinations.
So it looks to me like the system is just completely dead. Any ideas how
I can gather more information? Suspend/resume worked well in Fedora 12
and in the beginnings of Fedora 13 so I really want to have that feature
