Comment 0 for bug 788436

In Maverick, suspend and hibernate was working fine. After upgrade to Natty, when suspend or hibernate, the system is able to go into the suspend or hibernate mode, but not able to come back form it.

Tried the older kernel:
2.6.35-28-generic-pae
2.6.35-21-generic-pae

All works fine.

Logs and system information should already in the attachment.
