Re: GPF
You have provided only one important information (the problem), where is your source code that causes the #GPF and what does it try to do?

Hi,
Your IRQ handler is trashing the stack.

Re: GPF
Read my advice in the General Programming forum. Single-step through your interrupt code in a debugger and the answer should be obvious.
You have written interrupt handlers for all enabled interrupts, and set up the appropriate interrupt table of descriptors, haven't you?
