Summary: Radeon with KMS and UMA works only up to 128MB Product: Drivers Version: 2.5 Kernel Version: 3.3-rc7 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri@kernel-bugs.osdl.org ReportedBy: j.fikar@gmail.com Regression: No
Hardware: Asus M4A88TD-M EVO with integrated Radeon HD 4250 (RS780)
Description: in bios I can choose UMA from 32MB up to 1024MB, but only values up to 128MB work. Higher values lock the console in text mode before switching to KMS. It also happens on older kernels with KMS (2.6.27), but the console is not locked, the radeon module oopses and resolution stays VGA.
There is also option to locate UMA "above 4G" or "below 4G" in bios, it doesn't matter. Also it has 128MB of sideport memory, this option doesn't matter neither. (I have it off for now).
vramlimit parameter doesn't matter either.
System is x86_64, 16GB ECC DDR3 RAM.
