Hi folks, The 4.19.11 and 4.19.12 kernels include a patch from 4.20-rc6 that is defective and causes memory corruption. The patch was reverted upstream and will not appear in 4.20, but is still present in the 4.19 series. Stable kernels are quick to include upstream patches to core code that have not had the time to soak for a couple of weeks for assessment of the tree-wide impacts. Unless you are doing your own stable kernel QA on fstests & your own workloads, we do not recommend using stable kernels at this time. --D
