Don't worry, be happy. Next boot should recognize your change > (check the "avail memory" during boot process) Okay, this is exactly what I did - entered -c at the boot prompt - when it got to the Kernel Configuration Menu I selected CLI mode - entered iosize npx0 32768 - entered ls to verifier that the iosize of npx0 was set to 32768 (it was) - entered q It then panicked and rebooted as expected but after rebooting npx0 returned to the default and it panicked again.
