https://bugzilla.kernel.org/show_bug.cgi?id=207147 --- Comment #3 from John.p.donnelly@xxxxxxxxxx --- Hi Alan, wrt to comment 2. If that is the case that iommu=on is needed on that is fine. I just wanted to report my observation. FWIIW - 4.14 Oracle UEK5 kernels and 4.18 Redhat kernels do not require iommu=on to have the HP iLo devices operate. This is an operational difference between the 4.x and 5.x kernels. Our own Oracle servers do not exhibit the same failures as HP Gen9 and Gen10 do. They operation fine regardless of the iommu setting(s). -- You are receiving this mail because: You are watching the assignee of the bug.
