Sigh... We're running VM/ESA 2.2 which means CP doesn't know about the IEEE floating point hardware. As I see it, we can upgrade VM, tell the kernel to use emulation even though the hardware is there, or put Debian (and VM) into their own LPARs. Does crypto make heavy use of floating point? Is there a way to virtually network between LPARs? Does the kernel parameter support using emulation even when the hardware is available? If you can answer off the top of your head, let me know. Otherwise, I'll figure this out next week. -- May the LORD God bless you exceedingly abundantly!
