| Tehdastehdas | I have an ideological quarrel with Linux kernel development: | 09:25 |
|---|---|---|
| Tehdastehdas | Lenovo ThinkPads are in my opinion let overheat by the kernel bullheadedly sticking to standard procedure instead of using a workaround known to help many computers having overheating problems: setting the fan to maximum speed using fan control "disengaged" mode. I present my case here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1491797 from a different angle from the original slow fan bug report filed 2011 here: | 09:25 |
| Tehdastehdas | https://bugs.launchpad.net/ubuntu/+source/linux/+bug/751689 Result: won't fix: the assigned developer recommends to approach Lenovo with the problem, although it would be way easier to smarten up the kernel and get users to accept the kernel update than to have all affected users to fetch and install a BIOS update Lenovo hasn't even made yet. Yes, the root causes are Lenovo's faulty ACPI design and many laptop's barely suff | 09:25 |
| ubot5 | Ubuntu bug 1491797 in linux (Ubuntu) "Shuts down when supposed to suspend as a reaction to self-caused overheat, session lost" [High,Won't fix] | 09:25 |
| ubot5 | Ubuntu bug 751689 in linux (Ubuntu Precise) "[Lenovo Thinkpad x201s] Overheat due to slow fans when on 'auto'" [Critical,Confirmed] | 09:25 |
| Tehdastehdas | icient cooling system, but they can be worked around via software in many ways (non-standard maximum fan speed and/or CPU throttling and/or intermittent suspending to cool down), so I think it should be worked around as default, because Ubuntu is commonly used on these faulty machines, and the users are suffering. | 09:25 |
| apw | Tehdastehdas, ok. This is the machine which you have drilled holes in the case of ? | 09:44 |
| Tehdastehdas | yes, but I did drill the holes around the original intakes to avoid disturbing the designed flow pattern | 09:47 |
| apw | Tehdastehdas, as I see the position, this specific machine is not representative of its kind (x201s are pretty common in our circles), and that therefore a general solution is not going to work here. Did you try out using a specific thermald profile for this machine? | 11:29 |
| apw | ~. | 11:44 |
| diwic | wily is going to run 4.2, right? | 11:45 |
| tjaalton | yes | 11:46 |
| tjaalton | already is | 11:46 |
| diwic | tjaalton, we probably want to backport the i915 -> hda patch set there too, then | 11:47 |
| diwic | tjaalton, since that isn't in 4.2 | 11:47 |
| tjaalton | and the maybe 60 other commits for skl, yes | 11:47 |
| diwic | tjaalton, ok, fair point | 11:48 |
| tjaalton | now that they're in linus' kernel | 11:48 |
| apw | oh goody, 60 patches, you are making me _so_ happy | 11:49 |
| tjaalton | I haven't counted | 11:49 |
| tjaalton | but vivid just got >50 patches | 11:50 |
| tjaalton | though some of it was sync to current 4.2 | 11:50 |
