My patch will do nothing for the S3 resume problem. There must be some bug in the radeonfb power management code. The only way I can think to debug this is to put bunches of printks into drivers/video/aty/radeon_pm.c and then hook a serial console up to the laptop. That will let you see where the hang is. Once you locate the hang benh or I can try to figure out a fix. The technique works, it how I found a bug with disk drive initialization. You do need to build the serial driver in and turn on early printk support in kconfig. Check to make sure the serial console works before loading radeonfb. You may be surprised with you start getting some output, sometimes the drivers print a message saying exactly what is wrong. It may be possible to use kdbg over a serial line but I haven't tried that method. -- Jon Smirl [EMAIL PROTECTED] ------------------------------------------------------- This SF.Net email is sponsored by: NEC IT Guy Games.
