Public bug reported: Since upgrading to 11.04 (from 10.10) neither suspend nor hibernate are working any more.
The system just doesn't power down, i.e. power LED is ON, fans are rotating and the monitor doesn't power off. At that stage no input is possible any more, keyboard and mouse are non functional. I have to reset or shutdown the computer with the hard keys. After booting, the sound card (Soundblaster Audigy) is muted. (when booting from powered off state it isn't muted). I tried to do some self-debugging using the guidelines I found here: https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume Following the instructions, I found that neither suspending nor hibernating from text mode shows anything on the screen. Using the instructions for per-subsystem hibernate testing I was able to gather some info. Find it attached to this bug report. As suspend/hibernate worked in 10.10, this is a regression. Please help. I'll gladly submit further information if needed.
