AACRAID fails to initialize after an kexec operation

I am trying to kexec into 2.6.21-rc6-mm1 kernel on an x86_64 machine and
aacraid panics in the second kernel. Following is the panic message.

Any idea what's going on? Please let me know if more details are required.

Adaptec aacraid driver (1.1-5[2437]-mh4)
