      Well, I turned off Legacy USB and USB 3 in the BIOS, and the problem seems to have gone away.  It's now idling at a nice 39W. :)

      Will the output of the commands still be worthwhile?

        No - seems like a USB related problem.

          Actually, it looks like it's not. :(  It just took a while before it came back. :(

          Here's the output.

            I think Steve's suggestion was that you disable USB2 and USB3. From what you said you disabled USB1 and USB3. Please try Steve's suggestion. USB keyboard and mouse should work fine with USB1.

              I would try disabling 'high speed' with that loader tunable. You clearly don't need high speed, ehci, for a keyboard.

                I think Steve's suggestion was that you disable USB2 and USB3. From what you said you disabled USB1 and USB3. Please try Steve's suggestion. USB keyboard and mouse should work fine with USB1.

                Those were the only options in the BIOS for USB.

                @stephenw10:

                I would try disabling 'high speed' with that loader tunable. You clearly don't need high speed, ehci, for a keyboard.

                Steve

                I'll give that a shot.  Which ones do you suggest?  All three or just the last one?

                  I would probably try no_hs first then lost interupt.
                  The sysctl OIDs are listed in the 8.1 source code, here, but I don't have them on my system. Perhaps because I'm not using USB.  :-\

                    No luck with no_hs.  It ran fine for a little bit, but then quickly returned to it's previous state.  Is there a way to make sure that it's recognizing the loader.conf.local?

                    And I don't really have a choice on using USB.  I don't have any PS2 ports. :)

                        I get hw.usb.ehci.no_hs 1 when I do it.  So it's picking it up.  I guess it's time to try the others.

                          None of them worked.

                          Also, my keyboard no longer works.

                          Any other suggestions?

                            Some device drivers don't register sysctls until they have successfully attached at least one device. I don't know the specifics of the USB sysctls.

                            Suggestions:

                            • Use  a motherboard with a chipset that has been available for at least six months at the time of release of FreeBSD 8.1. (I recall that I saw an older pfSense release lock up on startup on a motherboard with AMD chipset if USB was enabled. The next version of pfSense which had a more recent FreeBSD worked fine on the same motherboard when USB was enabled.)

                            • Keep searching - maybe a FreeBSD user has found a solution for FreeBSD 8.1

                            • Ignore it, you still have three working cores which is probably much more than you need.

                            • Disable motherboard USB entirely and use a PCI USB 2.0 card (which almost certainly will have a  USB chipset that has been around for a while and consequently has well debugged drivers). I don't know if the BIOS will support this.

                            • Disable motherboard USB and set BIOS to ignore "no keyboard". What do you need the keyboard for once the system is configured.

                              That's what I thought, and yet:

                              Hmmm.  :-\

                              @Bai Shen. If it has disabled your keyboard it is clearly doing something. Do you still have Legacy USB disabled in the bios? Perhaps you have ended up disabling ehci when that is all that was left still functioning.

                                Not as far as I can tell.  There's a bug filed for it, but no resolution so far.

                                @wallabybob:

                                That's what I'm doing.  The biggest annoyance is that it prevents the processor from idling and therefore uses more power than it should.

                                @wallabybob:

                                Maybe.  But right now I'm using all of the PCI slots for NICs.  I'll be picking up PCIe NICs later, but for now I'm using the ones I have.

                                I've thought about doing that.  But I've had instances before where I had to use the console on the actual box to reset/change configurations.  So I'm hesitant to do that atm.  Plus I'm not sure how it'll work to turn it back on as there's no other way to connect a keyboard.

                                  No, I made sure to turn legacy and usb3 back on before messing with the loader.conf.local.

                                    I would definitely leave USB3 disabled.
                                    Perhaps you can force one of the two devices onto a different IRQ.

                                    Edit: It seems (though I can't find detailed instruction) that you should be able to set IRQ 16 as unavailable to PCI auto configuration. That should force your LAN card onto a different IRQ.

                                      I don't think it has a serial port, but I could be wrong.  I don't have any infrastructure to support that either.

                                      Yep, I'm running the latest bios.

                                      I'll have to look through the bios at the PCI config.  I don't recall seeing anything like that before, but I wasn't looking for it.  How does setting the NIC to a different IRQ fix the problem?  Wouldn't I still get the interrupts from the ehci?

                                        Because it's highly probable that FreeBSD didn't support it when 8.1 was released. Does it even support it now?

                                        It may be an IRQ conflict causing the interrupt storm.

                                        @Technical:

                                        Any interrupts set to Available in Setup are considered to be available for
                                        use by the add-in card.

                                        Implies that you can set to unavailable.

                                          Because it's highly probable that FreeBSD didn't support it when 8.1 was released. Does it even support it now?

                                          No idea.  I'm not using them, but figured I'd leave them on so I don't plug something in down the road and wonder why it's not working. :)

                                          It may be an IRQ conflict causing the interrupt storm.

                                          Ah, gotcha.

                                          Any interrupts set to Available in Setup are considered to be available for
                                          use by the add-in card.

                                          Implies that you can set to unavailable.

                                            I ended up being sidetracked by other things and never messed with the box any more.  This weekend, I shut it down to rearrange some cables.  Since I brought it back up, I haven't seen the problem again.  No idea what the difference is as I don't recall changing anything.

                                            Just wanted to give y'all an update.
