The new USB stack is a bit more stack hungry as compared to the old one that my RX2660 gets a machine check and spontaneously reboots at the time the USB DVD drive is found and attached to CAM as a mass storage device. This doesn't happen always, but definitely varies per kernel build. Likewise when using a 128-byte printf buffer. The additional 128 bytes that printf needs seems to be enough to have the memory stack and register stack collide and causing a machine check. Thus: Bump KSTACK_PAGES from 4 to 5. END
