The resulting kernel hangs on our SN hardware just after printing "All processors have done init_idle". Now it is possible this is something peculiar to the SGI kernels, but I was wondering if anyone knew of places in the IA64 kernel that "know" that sizeof(spinlock_t)=8 and don't work correctly if this is changed. -- Best Regards, Ray ----------------------------------------------- Ray Bryant SGI 512-453-9679 (work) 512-507-7807 (cell) raybry@sgi.com raybry@austin.rr.com Computers are like air conditioners.
