SubjectPCIE region size issue?
Date
Hi.

I purchased an AMD64 laptop last December, and have never had perfect success
in getting suspend to disk to work reliably. I thought maybe I had a bug in
Suspend2, but careful diagnosis kept pointing in the direction of drivers. In
addition, from time to time, the screen goes plain white and the system stops
responding, requiring a hard power off.

The other day, I saw a report of bios settings for the uma aperature not
matching what Linux was detecting. I checked my machine, and found that this
issue is occuring here. If I set the bios to 32 meg, lspci says it's 64, and
so on. If I set the bios to 256 meg, the system is unbootable. (Forgive me if
my terminology is a bit messed up - I'm not a pci expert!).

I've seen a number of other reports of issues with pci region sizes, not
always graphics related.

I'm therefore wondering, could there be some bug in the sizing of regions
that's leading to the sizes being doubled?

I have also emailed my laptop manufacturer to see if there are any bios
updates available.

Regards,

Nigel
