Hello While I have for the longest time used 4.5 as a base for my F/C jammer that I use every day here in our lab I recently added more jammer code so I decided to test this all on latest upstream. Booting the target server on my 4.5 kernel with jammer code is flawless and serves LUNS with no issues and handles the jamming also fine. However just building a 4.19.0_rc7+-1 (I left the jammer stuff out) its pretty broken. So: Has anybody used this recently on the later kernels, if so when was it last stable before I go starting to figure this out.
