Having 2 stacks was not really the problem. Since ia64 was the first "other" platform onto which KSE was ported, extra effort was needed to remove the inherent i386-isms. Not a biggy, but had to be done with care. The real problem is in having 2 different ways to enter the kernel (and leave again). Contexts created when we enter the kernel through path A cannot be restored while we leave through path B and vice versa... -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net
