I haven't run tboot in a while, but I'm trying it on my HP dc7800 and finding it hangs in GETSEC[SENTER]. This is even true with old versions of tboot that used to work. My system has no USB ports plugged in, and no hardware changes. The one change is I recently updated my BIOS. I suspect this has to be the cause. One nice thing about the new BIOS is that the tboot hang actually reboots the machine with the ERRORCODE register intact. Its value is c00020a1. This is progress code 0ah, error code 1000, meaning: "device scope of VT-d DMAR ACPI table is invalid". Not clear what this means. My log is attached, including the hang and the relaunch of tboot. This is version 20090330 of tboot. Thanks very much - Hal Finney |
