Without working TDCALLs the error message won't appear anywhere. The only practical way to debug such a problem is a kernel debugger.

Also printing an error message might end up recursing because the console write would trigger TDCALL again, or eventually stop because the console lock is already taken. In any case it won't work.

Yes, good point. In this case, adding debug print will not work. But I
can add more comments to the code.
