Hi. I compile and pack a rt patched kernel for the newest longterm kernel. Now i run 4.4.38 with rt49 patch. x64-v3:~$ uname -a Linux x64-v3 4.4.38-rt49 #1 SMP PREEMPT RT Mon Dec 19 10:28:46 CET 2016 x86_64 GNU/Linux x64-v3:~$ Is a blobed kernel (not strict free kernel). if someone send me a site or FTP to upload i can share the packages. I build bin, headers and source packages. sorry for my english. 2017-01-13 11:36 GMT+01:00 Ralf Mardorf <ralf.mardorf@xxxxxxxxxxxxx>: > On Fri, 13 Jan 2017 08:52:15 +0100, Alexander Dahl wrote: >>Ubuntu Studio > > Hi, > > I'm an Arch Linux user, but I'm helping users with Ubuntu flavours, > including Ubuntu Studio. > > The Ubuntu repositories provide a so called "lowlatency" kernel, > without the rt patch.
