Hello! Just a little question: Should an APM suspend to disk also save the MTRR table? As far as I can tell my notebook's APM BIOS does not do so. After resume the kernel still shows the old table but it is in fact empty. I discovered that by trying to remove an entry and the kernel then said that this entry is not there. After the first newly added entry the table is correctly outputted again. If the BIOS does not have to do so then I fear I found a kernel bug ;) Possible way around (from what I understood of APM so far): Install an APM notificating function for suspend/resume and save the table beforehand and restore it after.
I am still having trouble with this damn Mitac Mi6020 notebook and am slowly coming to the conclusion that the BIOS and board are completely screwed which causes Linux (any version) to freeze at completely random points. If the APM BIOS should save and restore the MTRR entries I would have a reason to claim warranty and return the thing to my dealer ;) in the hope to get another notebook (which eventually works correctly). So any help is absolutely welcome that could uncover design flaws so I have more evidence to return the thing and never see it again. Thanks in advance! CU nils
