When I suspend to ram, the screen "melts" to all white and stays that way while the machine is suspended. When I resume, all is well. Nobody else on the linux-dell-laptops list seems to be having this problem, even people with what appears to be the same hardware. It happens with my custom kernels (I've tried 2.4.19 and 2.4.20) and the stock Debian 2.4.19 (all with apm, not acpi). All three of these kernels work correctly on other I4100 and I4000 machines I have access to. Suspend to ram works fine under Windows on the I4150. The problem happens even if I shut down X windows and rmmod the radeon and agpgart modules before suspending. I'd like to try to debug this. What further information can I provide?
