>Description:
When trying to compile my own kernel with "device pst" in configuration file, process fail with message:

2 errors generated.
As we see from /usr/src/sys/dev/pst/pst-iop.h, initiator_context and transaction_context fields of driver message struct are declared as u_int32_t, which doesn't match pointer size on 64-bit processor.
>How-To-Repeat:
On amd64 machine include
device pst
in your config file and try compile kernel.
>Fix:
The controller is very old hardware and one of fix may be exclude it from available devices on amd64 platform.
