I am testing the eth ports and thus I am pining on both internal ports and I
am also pinging the box from another server on eth1.
Within 1 min I received 4.92062e+06 Interrupts on eth1(not bad for a 2 way
ping) and 130 Interrupts on eth0 for the 1 way ping.
The timer interrupts are 5992 which I would say pretty good for a hand reading
You can also see completly different behavior on the ports and a jamming don't
ask me where it is coming from. The box has no other task to preform.
Can anybody make any sense out of that ?
I changed the debug level for the eth driver. It returns every few seconds:
APIC error on CPU1 : 02(02) (i know not an eth message, but it pops up at
APIC error on CPU0 : 02(02) the same time)
vortex_error(), status = 0xe481
vortex_error(), status = 0xe281
vortex_error(), status = 0xe681
vortex_error(), status = 0xe081
The vortex error may be 1 to 4 messages and either one is possible in any
combination
I attach the readings

The blocks of 5 return at the same time , as the time differnce is always 1sec
off look pretty nasty
