An interesting oops -- it appears that this one is a case not with the
ldt being out of sync with the tss, but that one of the entries in the
ldt is bad. The patch for the ldt code takes care of a problem with the
ldt not being reloaded properly, but it has no way to ensure that
changes to the ldt will be valid for _all_ tasks using the ldt.

I'm still pondering this problem, but don't have a workable solution
yet.

Regards,
Bill
