Hello RT Folks! I'm pleased to announce the 4.4.208-rt191 stable release. This release is just an update to the new stable 4.4.208 version and no RT specific changes have been made. Note the patch "x86/ioapic: Do not unmask io_apic when interrupt is in progress" has been dropped from the queue because stable gained the commit 2d63906f8a78 ("x86/ioapic: Prevent inconsistent state when moving an interrupt"). You can get this release via the git tree at: git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git branch: v4.4-rt Head SHA1: ba5eb0751f977d70dc5843195072547acf2de362 Or to build 4.4.208-rt191 directly, the following patches should be applied: https://www.kernel.org/pub/linux/kernel/v4.x/linux-4.4.tar.xz https://www.kernel.org/pub/linux/kernel/v4.x/patch-4.4.208.xz https://www.kernel.org/pub/linux/kernel/projects/rt/4.4/patch-4.4.208-rt191.patch.xz Enjoy!
