Hi. Currently I'm not in city, so I still didn't tested other kernels. I plan to test 5.1 with 3.10 kernel on BRASes (possibly it also has a regression), and I plan to try to assemble 4.1 kernel (it should be long-term - http://www.itworld.com/article/2938517/linux/linux-kernel-4-1-lts-released.html) and run it on some BRAS. Also, 4.1 provides scsitarget driver in kernel
5.0.x BRAS with 3.2.28 kernel is pretty stable (uptime is near 2 years). I filed bug to kernel's bugzilla - still no answer: https://bugzilla.kernel.org/show_bug.cgi?id=100971 07.07.2015 17:06, kp kirchdoerfer пишет: > Am Sonntag, 5.
