Ubuntu Hibernation on AMD Duron

[Raphael Derosso Pereira]

Hello,

I would like to tell you that Ubuntu Hoary Hibernation wasn't working on my 
ADM Duron.

It showed up the "Schedule while atomic" message and didn't execute the 
resume.sh script.

I digged the problem down and found a workaround that I want to share with 
you.

The patch is just below. In essence, it just put the hibernation call on 
another exclusive bash. That isolates the atomic scheduling problem, and 
guarantees the execution of resume script.
Besides this patch, I also needed to add the resume=<my_swap_partition> on 
grub kernel options.

I'm not subscriber of this list, so if you want to reach me, please send it 
privatelly.

Hope I helped!

P.S.: The sleep 10 could be reduced... I haven't tried, but I think 2 might 
do the job...
