So it seems related to the DRI after all. Though you're right it doesn't seem related to Mesa, so feel free to move this to the dri-devel list. When X runs with the DRI enabled, does grep radeon /proc/interrupts show the Radeon's interrupt line being shared by other devices? Does its count increase as well? In order to find out what's going on, I'd start by instrumenting the DRM functions radeon_driver_irq_handler() and radeon_acknowledge_irqs() (in radeon_irq.c) to find out if the former returns IRQ_NONE, whether the interrupt status register has any bits set other than those the DRM is interested in, etc. -- Earthling Michel Dänzer | http://tungstengraphics.com Libre software enthusiast | Debian, X and DRI developer ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
