Comment 92 for bug 160763

Cool, much thanks Maxim!

The bug should not be closed though, since it's not fixed in Maverick yet. I've also opened a task for Lucid since the patch could be backported to benefit Acer users.

For kernel developers, here's the commit message:

ACPI: Store NVS state even when entering suspend to RAM

https://bugzilla.kernel.org/show_bug.cgi?id=13931 describes a bug where
a system fails to successfully resume after the second suspend. Maxim
Levitsky discovered that this could be rectified by forcibly saving
and restoring the ACPI non-volatile state. The spec indicates that this
is only required for S4, but testing the behaviour of Windows by adding
an ACPI NVS region to qemu's e820 map and registering a custom memory
read/write handler reveals that it's saved and restored even over suspend
to RAM. We should mimic that behaviour to avoid other broken platforms.
