And if you start the slave before the master, this does not happen?
yes, it is!
What versions are you using: RTnet, Xenomai or RTAI, kernel & I-pipe
patch?
I use RTNet 0.8.3 and RTAi 3.1

Let's try something new (at least when it comes to remote-diagnosis of
RTnet):
--- drivers/rt_8139too.c (Revision 1106)
+++ drivers/rt_8139too.c (Arbeitskopie)
@@ -1722,6 +1722,7 @@ static int rtl8139_interrupt(rtdm_irq_t
boguscnt--;
} while (boguscnt > 0);
if (boguscnt <= 0) {
+ ipipe_trace_freeze(0);
rtdm_printk(KERN_WARNING "%s: Too much work at interrupt,
"
"IntrStatus=0x%4.4x.\n", rtdev->name, status);
/* Clear all interrupt sources. */
Apply this patch to the driver, switch on CONFIG_IPIPE_TRACE (=> Kernel
hacking), and rebuild both kernel and RTnet. When the driver is about
the complain, a backtrace will be captured. You can obtain it later via
/proc/ipipe/trace/frozen. Do an "echo 1 > /proc/ipipe/trace/verbose" and
"echo 10000 > /proc/ipipe/trace/back_trace_points" to enhance the
reported trace. Pack the result and post it.
The tracer will definitely work with Xenomai (kernel <= 2.6.19, tracer
fixes for 2.6.20 are pending), but RTAI /should/ be fine as well (but
I haven't tried for a year or so).
