I have been reading over the mailing list and reading over the LinuxBIOS code trying to get a feel for things but I am in need of some wisdom.
It seems LDTSTOP is not used by the LinuxBIOS for the most part and I am curious why. What I have gathered so far is that it is system specific (Southbridge?) to trigger. I found some mailing list mentions of old code from years ago that is no longer in the current tree.
I am searching for a way to disable and re-enable HT links for various reasons _without_ performing a reset (for example changing link speed/width or enabling/disabling devices at runtime). It seems that LinuxBIOS has chosen to not use LDTSTOP and just use resets instead. Is this a workaround due to the difficulty of implementing LDTSTOP?
I am using a Tyan K8SRE (S2891) motherboard. The board has an Nvidia nForce 4 Pro (CK804).

Dan Johnson
