Hi All,
I am very new to this type of stuff... Actually I am trying to use a PCMCIA based data card on a ARM architecture.... When ever I plug in the data card, /var/log/messages show following log... Even this log is repeated whenever I dial PPP. My Kernel Version is '
2.6.14' and card uses a serial driver.
Any help in this regard is greatly appreciated...
Regards,
Anoop
