Lots of different ones ha= ve been reported, but no Dell or HP systems. No Asus, It is clearly something = that ONLY impacts Lenovos and it looks like it can be further constrained to ThinkPads. I find no references to IdeaPads or other Lenovo lines. Last I k= new, development of ThinkPads was still in the US at the former IBM facility. Lo= oks like something unique to those systems, which is clearly distinct from other laptops. I just can't begin to guess what. This is WAY beyond anything I can troubleshoot, but I'm more than willing to help test. My L15 has been a real pain, unlike every other ThinkPad I've us= ed (and that is going back to at least 1995). I suspect that this will require= at last on and maybe two very top-line FreeBSD folks to track down. kib or jhb, perhaps? Now that 13 is out the door, there will only be more reports and I= 'd really like P-States. --=20 You are receiving this mail because: You are the assignee for the bug.=
