Rewriting Intel PCI bridge prefetch base address bits solves nvidia graphics issues
Hi,
We are facing a suspend/resume problem with many different Asus laptop
models (30+ products) with Intel chipsets (multiple generations) and
nvidia GPUs (several different ones). Reproducers include:
1. Boot
2. Suspend/resume
3. Load nouveau driver
4. Start X
5. Observe slow X startup and many many errors in logs (primarily
nouveau fifo faults)
or
1. Boot
2. Load nouveau driver
3. Start X

I wonder if you are experiencing the same issue. Do you have a list of
affected models, an acpidump, the output of "lspci -nnvvvxxxx" and the
corresponding BIOS version (e.g. from /sys...

Just to be sure, after "sleep", do both devices report "suspended" in
/sys/bus/pci/devi...
