aegiapHello, I have an issue on kernel 4.15.0-20-generic with Ubuntu 18.04 in a Xen environment. When I detach a network interface, the task hangs (see https://gist.github.com/aegiap/2cd469f3eb72903f97952473d329905e).09:11
aegiapThe patch https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c2d2e6738a209f0f9dffa2dc8e7292fc45360d61 seems to fix the issue. I was wondering if there is plan to backport it in a new release of the Ubuntu kernel for 18.04 ?09:13
apwaegiap, do you have a bug filed in ubuntu about this, with these details in it ?09:31
aegiapapw: not yet, I will create one.09:33
femmejsalisbury: the kernel logs dont seem to say anything about mooting the mainline kernel /without/ iommu=soft. Should I include the iommu=soft kernlog? Or is there another way to get the relevant logw10:45
jsalisburyfemme, no logs needed.  We just needed to confirm to upstream that we tested mainline and it still had the bug.11:34
