[ros-diffs] [ion] 24767: - Purposefully add 6 debug prints to RtlpGetRegistryHandle, which, while ndis.sys is initializing, should BSOD the system. I have seen this "RtlpGetRegistryHandle" BSOD randomly during boot (But always with the same stack trace), and a local HAL patch managed to cause it 100% of the time. I know that the problem had nothing to do with the HAL or registry paths, because it came up before too when I added debug prints to fstub. These 6 prints 100% reproduce the problem on my machine with GCC 3.4.5. It is my hope it will do the same for everyone. This is a nasty bug, either stack related or some critical structure is being damaged. I am breaking trunk because it's been here for a long time, but now I found a way to repro it so that we can work together to try finding it. In a way, trunk was always broken, but this patch should force a freeze. Please help.
