The trap is from an event queue overflow (ie. someone is generating too many
events too fast).

Check out the memory starting from 0x03e40 (use the DS register for your
segment selector) using the ‘dd’ command (ex. dd ds:0x03e40). This is the
event stack, and in it is the addresses of the ‘events’ (proxies), you can
use the /p command with the value from the stack (along with the ds
register) to get the proxy information and who it belongs to. Then use /P
for the owner PID to get process information on who that proxy belongs to.

Hopefully you’ll be able to identify who and why they might be generating
all those events.

It means that those events got generated before we could come out of the
kernel. Too much interrupt traffic could potentially do that, holding off
the exit squence where we process these events.

What does the proxy associated with openmem2 represent (what is it triggered
on)? What is going on in the system when the failure happens?

i use a timer in openmem2.the timer trigger every second.
if not in debugger mode, after failure,all process halt(i think),no console
response, no screen refresh. after reboot, i renice shell’s priority to
29,same as before.then i wrote a simple program that using rtc’s second
alarm interrupt,in interrupt handle it trigger a LED.when system hung up the
led still can blink for half hour.
in my system,irq3,irq4,irq5,irq7 used by serial port,net use irq11,no
parallel port,no harddisk,do floppy,whit a 32M diskonchip.

Are you changing ‘time of day’ around while this activity is going on?

What is the processor speed/mem/baud rate of the serial ports? Does the
crash happen if there isn’t any serial traffic?

pid_t far Clockhandler(void)

outp(ClockAddr,ClockRC); //RTC register C
tmp=inp(ClockData);
if(tmp&0x40) {//125ms periodic interrupt. i modyify RTC’s register A =
0xad
//and enable peridic interrupt.

switch (index) {
case 0:
outp(0x2f8,0x2a);
index++;
break;
case 1: // do i need _disable()?
outp(0x20,0x0a);
outp(0x2f8,inp(0x20));
index++;
break;
case 2:
outp(0x2f8,0x2b);

outp(0x20,0x0b);
outp(0x2f8,inp(0x20));

outp(0x11a,s); // run led

is this means ethernet(irq11) interrupt require can not be process?
irq3 & irq4–> serial port chip on PC104 CPU board,irq11–>rtl8139c on PC104
CPU board.
irq5 → two 16c554 chip on 8 serial port board (advantech PCM-3643).
irq7 → two 16c554 chip on another 8 serial port board (advantech
PCM-3643).

Well it’s hard to tell if the request for IRQ11 was processed, and a new one
is pending, or if it’s the original request.

You could attach a hander to all those IRQs and with counters see if there
is some starvation going on.

Hi,
I found the problem.
IRQ11(EtherNet) is very busy while system process hangup. Is hardware fault
or net.rtl driver bug? Net chip is rtl8139c on PC104 board(arbor

There are 10~200 times interrupts on IRQ11 every second normally.
