So using the s3c2410-fb/lcd driver is the wrong approach. The correct driver to use would be the s3cfb. Take a look at mach-smdk2416.c which uses this driver. The init for the s3c2443 should probably be similar. Also the irq you requested is a parent irq to different lcd-irqs in the sub- register on the s3c2443 and s3c2416. Therfore requesting it directly is disabled by the irq-subsystem. Hope that helps Heiko > > The interrupt is not busy by something else.
