Kernel bug mailing lists
by Laura Abbott 31 May '18

31 May '18

Hi, This is a friendly reminder that the kernel has some aliases to help with specific kernel bugs. When bugs related to a specific subsystem come in, you can add the alias in cc for more help in looking at the bugs. The kernel is big and we rely on other kernel experts to keep things running. The current list of aliases is at https://fedoraproject.org/wiki/KernelBugTriage#Triage_Quickstart The people on these aliases are managed in ansible. We're also open to adding new aliases if there's interest. Thanks, Laura

Some more info on this, the user with a x250 is reporting the problem is hard-freeze about once a day, which goes away when disabling LPM, so if you have a 50 series Lenovo laptop and are seeing the occasional hard-freeze this may be the cause.

Serious problem with SATA LPM in F28 on Lenovo 50 series laptops
by Hans de Goede 29 Apr '18

29 Apr '18

Hi All, I'm sending this to the fedora-kernel and -devel lists both to get the kernel team aware of this and because it is not entirely clear to me how to best deal with this. I guess we should get this added to the release-notes / common-bugs page for F28, but I'm not sure what the procedure is for that ? I've just become aware that at least for some users the use of SATA LPM in F28 causes the Lenovo 50 series laptops (confirmed X250, T450s G50-80) freeze/ hang hard under certain conditions when using SATA LPM, independent of the disk used (*). This is currently being tracked in: https://bugzilla.redhat.com/show_bug.cgi?id=1571330 A known workaround is to add: "ahci.mobile_lpm_policy=0" to the kernel boot command line. Can someone help me to get this documented? Once we've figured out what is going on I hope to be able to fix this with a kernel update, but people may still need the workaround to install Fedora 28. Also if people are using Fedora 28 on a 50 series Lenovo laptop without issues, please let me know. 3 independent reports points to a common problem, but maybe there is some other factor in play. Regards, Hans *) So blacklisting disks by their model string which is the normal way to workaround LPM issues does not work.

SPECK crypto cipher
by Peter Robinson 25 Apr '18

25 Apr '18

Thought I'd ask this one on list for reference. So in 4.17 upstream added the SPECK cipher [1] but for reference the ISO has rejected it (and SIMON) due to being designed by the NSA [2], not sure it specifically matters for Fedora but I thought I'd put the question out there if there's any thoughts or opinions on it. I believe from a Linux perspective it's currently primarily used on low end android phones that don't have HW crypto offload so it might not even be widely used in Fedora.

Custom compiled 4.17 kernel has a file conflict with COPYING for kernel 4.16
by stan 12 Apr '18

12 Apr '18

Hi, I built a custom kernel from the src.rpm for 4.17.0.0. When I tried to install it, it failed with errors like the following: Error: Transaction check error: file /usr/share/licenses/kernel-core/COPYING from install of kernel-core-4.17.0-0.rc0.git4.1.20180407.fc28.x86_64 conflicts with file from package kernel-core-4.16.0-0.rc6.git3.1.20180325.fc28.x86_64 But this is just the GPL v2 license. Did the kernel change its license? And, if it did, how do I make the transition, other than force installing the new version? Thanks.

Kernel 4.16 rebase plans
by Jeremy Cline 02 Apr '18

02 Apr '18

Hi folks, 4.16 was released on Sunday and will soon be in the rawhide and Fedora 28 updates-testing repositories. Fedora will be following the same rebase procedure as previous releases: after a few stable releases, typically 4.16.2 or 4.16.3, Fedora 27 will be rebased to 4.16. Fedora 26 will be rebased shortly after that. This should all be complete by the end of April. Regards, Jeremy
