Subject: Fwd: System will crash when trying to wake up from second suspend

Hi,

I notice a bug report on Bugzilla [1]. Quoting from it:

> Total carbon copy of the following bug in terms of symptoms described, warning displayed after needing to hard restart after failed second suspend, and solution, but with a different laptop vendor and an A10-5745m APU instead of the A6-6310: https://bugzilla.kernel.org/show_bug.cgi?id=189431
> 
> The problem occurred on the latest stable patch of Debian 12 at the time of writing, as well as Arch Linux using the latest lts kernel at the time of writing, mainline Arch kernel 6.5.9 as well as the testing Arch 6.6 kernel.
>  
> changing linux/drivers/acpi/sleep.c

Evidentially, the HP envy m6 sleekbook needs nvs memory despite being manufactured after 2012. Bios is at the latest available version provided by HP.

See Bugzilla for the full thread and proposed fix patch.

Thanks.
