However we are getting RT regressions with the generic kernel. Digging deeper into this option, it seems to be pretty specialized and to require quite a bit of workload-specific configuration/tuning to be useful, so it doesn't really seem to make sense for a general-purpose kernel. Fix: Turn this option back off. Test Case: See comment #4. Regression Potential: This was turned on to support some docker functionality, so this functionality will no longer be available. We've had this option off for all releases prior to focal, so this seems acceptable. --- These errors started right after upgrading to 20.04.
