[Kernel-packages] [Bug 1690395] [NEW] CPU fan always on with kernel 4.10.0.20.22 (zesty) on a X1 Carbon 5th gen
Public bug reported: Once the CPU fan is turned on, it never turns back down, even when things have already cooled down and CPU usage is low (<2%) for 5+ minutes. The same cannot be reproduced with the previous kernel version (4.10.0.19.21), on the same machine.

[Kernel-packages] [Bug 1475434] Re: ipvlan module causes kernel crashes (backport fixes from upstream)
I failed to mention that I also had linux-image-extra-3.19.0-26-generic and linux-headers-3.19.0-26 from vivid-proposed, but it is probably not relevant: $ uname -r 3.19.0-26-generic $ apt-cache policy linux-image-extra-3.19.0-26 linux-image-extra-3.19.0-26-generic: Installed: 3.19.0-26.27 Candidate: 3.19.0-26.27 Version table: *** 3.19.0-26.27 0 400 http://us.archive.ubuntu.com/ubuntu/ vivid-proposed/main amd64 Packages 100 /var/lib/dpkg/status $ apt-cache policy linux-image-3.19.0-26 linux-image-3.19.0-26-lowlatency: Installed: (none) Candidate: 3.19.0-26.27 Version table: 3.19.0-26.27 0 400 http://us.archive.ubuntu.com/ubuntu/ vivid-proposed/main amd64 Packages linux-image-3.19.0-26-generic: Installed: 3.19.0-26.27 Candidate: 3.19.0-26.27 Version table: *** 3.19.0-26.27 0 400 http://us.archive.ubuntu.com/ubuntu/ vivid-proposed/main amd64 Packages 100 /var/lib/dpkg/status $ apt-cache policy linux-headers-3.19.0-26 linux-headers-3.19.0-26: Installed: 3.19.0-26.27 Candidate: 3.19.0-26.27 Version table: *** 3.19.0-26.27 0 400 http://us.archive.ubuntu.com/ubuntu/ vivid-proposed/main amd64 Packages 100 /var/lib/dpkg/status -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1475434 Title: ipvlan module causes kernel crashes (backport fixes from upstream) Status in linux package in Ubuntu: Invalid Status in linux-lts-vivid package in Ubuntu: Invalid Status in linux-lts-vivid source package in Trusty: Triaged Status in linux source package in Vivid: Fix Committed Bug description: SRU Justification: [Impact] ipvlan is currently unusable as removing an interface with an IP address attached will cause a kernel crash. [Test Case] As reported in this bug, doing the following will result in a kernel crash: ip netns add ns0 ip link add link eth0 ipvl0 type ipvlan mode L3 ip link set dev ipvl0 netns ns0 ip netns exec ns0 bash ip link set dev ipvl0 up ip -4 addr add 192.168.0.10/24 dev ipvl0 ip link del dev ipvl0 [Fix] commit 27705f7085ce2e124fac4c280ce824962cc90bb6 Author: Jiri Benc Date: Sat Mar 28 19:13:22 2015 +0100 ipvlan: fix addr hash list corruption -- Kernel version 3.19, currently being used as the vivid LTS kernel, includes support for ipvlan. But at its current state it is unusable as simply removing an interface with an ip address attached will cause a kernel crash. The fix is already upstream: https://github.com/torvalds/linux/commit/27705f7085ce2e124fac4c280ce824962cc90bb6 Reproducing this is easy (requires a recent version of iproute2, with support for ipvlan, such as the one in debian/experimental): ip netns add ns0 ip link add link eth0 ipvl0 type ipvlan mode L3 ip link set dev ipvl0 netns ns0 ip netns exec ns0 bash ip link set dev ipvl0 up ip -4 addr add 192.168.0.10/24 dev ipvl0 ip link del dev ipvl0 The last line will cause a kernel crash, with a calltrace that looks like this: https://gist.github.com/fabiokung/b360cb2f3bdf2fb36c8b Can we get the fixes backported to the 3.19 LTS kernel from vivid?
