YOU DROPPED THE MAILING LIST AGAIN !! HOW MANY TIMES DO I HAVE TO TELL YOU TO 
KEEP IT CCED ?!

> Even if I assign 0x1234 to MSC2 I am getting the same timeout problem.

Because 0x1234 is 16 bit bus ... dont you use 32bit bus to that card ?

Check the bus with a scope I guess, that should give you some ideas.

You can enable debuging output in the smc91111 driver.
