IPTS not functioning after sleep on 5.5 kernel #128
Description
IPTS does not work after suspend/resume cycle. Wiki states to report this issue if its still not working on 5.5 kernel. I can work around the problem by removing ipts before suspending and adding after resume but this does not work automatically.
