Ok, problem is that device_power_{down,up} is right thing, and neccessary for many machines to work... ...so... could you go through sysdev_register()s, one by one, commenting them to see which one causes the regression? That driver then needs to be fixed. Go after mtrr and time in first places. Pavel PS: Probably drop andrew from reply; he probably gets enough mail anyway. I want this one to go to him so that he does not back up the patch, through. -- People were complaining that M$ turns users into beta-testers... ...jr ghea gurz vagb qrirybcref, naq gurl frrz gb yvxr vg gung jnl!
