Summary: radeon interrupts don't fire with MSI Product: DRI Version: DRI CVS Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: tdroste@gmx.de
Created an attachment (id=37470) --> (https://bugs.freedesktop.org/attachment.cgi?id=37470) dmesg without MSI
If I boot the current d-r-t kernel with MSI enabled the radeon module doesn't fire any interrupts. Without the interrupts and vblank_mode in driconf set to 3 the screen stops refreshing.
This is always reproducible. To make it work again I have to boot with pci=nomsi.
Software versions kernel current d-r-t (2.6.35-rc2) ddx, mesa, xserver git master
Hardware Radeon X1950pro RV570 (AGP)
