Re: Suspend to RAM very slow on R600?
My hunch is mostly based on what I've seen in the linux-acpi mailing
affecting some toshiba laptops.
If you haven't reported this anywhere yet, I recommend you report it
using a command like this on a terminal:
and also quite possibly in the same bug attach your DSDT table info.
To compile your DSDT information, install if you haven't already the
acpidump and iasl tools:
sudo apt-get install acpidump iasl
Then run the following commands:
sudo acpidump > acpidump.txt
sudo acpixtract acpidump.txt
iasl -d DSDT.dat
ls -l DSDT.dsl
This will create a DSDT.dsl file that you can attach to the bug report.
