Alan, do you remember when the default usb-handoff went in effect? This smells like the one. Yes, i8042 is mostly emulated these days. Laptops were emulated for a very long time. Servers still ship with real i8042, until Intel stops making southbridges with it. I am afraid that Len is hitting an SMM BIOS bug here. I saw such things with RHEL. Basically, even if we take controllers away from BIOS with the handoff procedure, the BIOS still manages to get involved into the bus sharing between EHCI and its companion OHCI, even though it shouldn't. Dell shipped updates for BIOS on the PE 380 for that reason, to name one example. -- Pete ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
