Hi , Thank for all valuable advice. I have checked the spec of Wireless LAN PCMCIA card, the wait signal is longer than the setting of BMT. That explain why we have the machine check. My fix is modify the the Machine Check Interrupt handler when read or write PCMCIA because we still need monitor Machine check in some case and The driver work fine now.
