dual processor and raid

[Don]

Hi,

my box works fine on this mylex extremeraid 1100, but when i compile the box for smp it will freeze at mounting from the raid card, i only compiled smp changed nothing else in the kernel, and it will just sit and hang and mounting /dev/mlxXXXX  if i reboot it and wait it will do filesystem checks then still hang, but if i load the old kernel or dont compile in the second processor it works fine, it does say  SMP CPU #1 launched in the startup msgs, and this system use to work dual processor before the raid card. any ideas?

thanks,

Don
