Alright here it is.

Is it already too late to have this merged in 14.2?

I'm pretty sure this patch is safe. GFP_NORETRY isn't used in-tree at all right
now. And this patch makes it do pretty much what it says. It doesn't retry.
You'd hope that any code using this flag would expect allocations to fail...

The problem doesn't always happen for everyone but when it does man it's rough.
After a week or two I was getting hangs that lasted 15 seconds sometimes.
Restarting firefox would fix it for a while but eventually it becomes unusable.

Even if this made it in 14.2 IIUC it would take a while before the 14.X
packages would be compiled against the new kernel headers, but it would already
be useful to have it in base so that you could get the fix by compiling
drm-kmod from ports.
