The UART and/or driver already Just another data point: Seems that the interrupt rate doubled for drm0 on my system (from 60 to 120 driving a LCD at 60Hz vertical refresh). I thought this might be a problem with shared interrupts (drm0 and xl0 shared APIC IRQ 16), but removing the (actually unused) xl driver did not make a difference ... Regards, STefan
