Product: ACPI
Version: 2.5
Kernel Version: 2.6.35 and newer
Platform: All
OS/Version: Linux
Tree: Mainline

patch to add machine to the blacklist
How to reproduce on Sony Vaio VGN-FW21M:
- make the laptop suspend
- press any key
- laptop reboots (instead of resuming).
Adding acpi_sleep=nonvs to the boot command line fixes the problem, computer
resumes just fine.
As this is a regression (it used to work some years ago and the bug was
introduced with 2.6.35, as far as I can tell), I think it would be good if a
fix also found it's way down to stable kernel releases.
According to the following commits
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=72ad5d77fb981963edae15eee8196c80238f5ed0
and

this system just needs to be added to the blacklist in
drivers/acpi/sleep.c
in order for suspend/resume to work out of the box (again).
I attached a patch that adds this system to the blacklist. Suspend/resume works
fine with the modified kernel, without the need for the extra boot parameter.
The patch was created against the most recent (at the time of writing) kernel
master branch.
