[ltp] R51 doesn't resume from Suspend to ram properly

[Niels Stargardt]

Hi Jan,
I'm sorry that I not really an kernel expert, but I have 3 hints which could eventually help:
1. Use the newest BIOS and ACPI-Patches.
2. Try to switch with Strg+Alt+F1 to console. Suspend to ram then and wake up. Perhaps this will work.
3. Try to remove as much modules as possible, perhaps one of it makes the trouble. A more sophisticated approach is to try to find out which module is responsible for MCE or Bank 1.

Hope this is useful

	Niels
