>Description:
Cannot debug system call, trap. Is it at all possible to debug with target sim for my own os? I've tried with an option:

target sim -r 0x404000 -e bug

But I am always getting a following failure(for a trap):
...
(gdb) cont
cpu 1, cia 0x700: double interrupt - MSR[RI] bit clear when attempting to deliver interrupt, cia=0x700, msr=0x1000; srr0=0x21c4(cia), srr1=0x21002(msr); trap-vector=0x700, trap-msr=0x1000

Program terminated with signal ?, Unknown signal.
The program no longer exists.
(gdb) 
...

Am I doing something wrong?
Is there any other option/alernative/patch how to solve it?

thank you for any hint

P.S. Is there at all some command to show a current device configuration?

int main(void)
{
   //asm("sc");
   asm("trap");
   return 0;
