Public bug reported: [Impact] NVIDIA GPU becomes unusable after S3.
[Test] The NVIDIA GPU works well after applying this patch. [Fix] Rewrite 0 to Intel PCI bridge 'Prefetchable Base Upper 32 Bits'. This should be done by BIOS S3 code [1], but now the issue reappears, let's do the same via Linux PCI subsystem. [Regression Potential] Low. After applying this patch I haven't noticed any change on already working PCI devices. Also this patch is acked by PCI and ACPI maintainers, so we can be more confident.
