Re: Error: kernel cannot suspend to ram.

When running on the console the command 'pm-suspend', I get the following:

Any ideas?

The kernel thinks this machine can not suspend to ram.


Let me indicate in addition the specification of my kernel:

$ uname -r
2.6.22.9-91.fc7

You can also tell us what your PC/Laptop is, hardware profile (if
using smolt) or 'lspci' & 'cat /proc/cpuinfo'.

Thanks, Doncho.
