https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D226495 --- Comment #3 from rkoberman@gmail.com --- (In reply to Carlos J. Puga Medina from comment #2) Thanks for the suggestions, Carlos. I seem to have a dilemma. I need to have VTd enabled to support my Windows 7 virtual system, so the question is whether VTd with semaphore is more stable than VTd without it. >From the blog, it is not clear to me that enabling rc6 is related to my pro= blem or just a good thing to do. In any case, I had already been running with it= set to '5'. There was a note that a bug in Sandy Bridge could lead to hangs if = bit 1 was set, though a later note indicated that an update to the DRM code mig= ht disable that optimization on affected Sandy Bridge systems. This is from old memory as I have been running it at '5' for several years. I'll monitor for errors and see of the semaphore makes things better or wor= se. Finally, where did "Robert" come from? I have not used that name for almost= 60 years, though that is my first name. I started using my middle name in first grade. I'd like to find the source of any such reference and squash it, if possible. Again, thanks! Kevin --=20 You are receiving this mail because: You are the assignee for the bug.=
