^Cqemu: terminating on signal 2

But if i attaching with gdb, i have infinite loop in diag_init. There is my 
backtrace:
170         if (outp) {
(gdb) 
181         status = inb(CMD_PORT);
(gdb) 

182         if ((status & 0x01) == 0) {
(gdb) 
183             continue;
(gdb) 
217     }
(gdb) 
170         if (outp) {
(gdb) 
181         status = inb(CMD_PORT);
(gdb) 
182         if ((status & 0x01) == 0) {
(gdb) 
183             continue;
(gdb) 
217     }
(gdb) 
170         if (outp) {
(gdb) 
181         status = inb(CMD_PORT);
