Would you be able to attach some of the error message so we know where  
we could start?

Also, in userland after you make a call to L4_Ipc(), you can check  
whether the IPC has succeeded by:

blah()
{
	L4_Word_t failed_phase, ipc_error_code;

	L4_Ipc(); /* includes L4_Send(), L4_Call(), L4_ReplyWait() etc... */

	failed_phase = L4_IpcError(L4_ErrorCode(), &ipc_error_code);
}

Please see libs/l4/include/types.h for numerical definitions.

 From your description, though, it looks like the error occurred in  
the kernel?  Please clarify.
