Hello,
I'm trying to build an OpenBSD pf cluster using 6 interfaces, 2 Intel 1000
onboard with chipset 82547GI, and a quad port Intel 1000 nic (PCI-X) with
chipset 82546GB.
Trying to ping the switch connected to one of the quad ports gives me the
following terrible results:
PING xx.xxx.xxx.xxx (xx.xxx.xxx.xxx): 56 data bytes
(...)
--- xx.xxx.xxx.xxx ping statistics ---
21 packets transmitted, 20 packets received, 4.8% packet loss
round-trip min/avg/max/std-dev = 1.822/43.125/161.863/34.999 ms
I have tried to change IRQ configuration and this is the best result I
managed to get. I had even worst results, including a total machine lockup.
I'm using OpenBSD 4.2 with all available patches. I have disabled stuff like
USB, LPT and serial ports.
It appears to be an IRQ conflict problem. The only thing that can't be
changed at BIOS is onboard ethernet irqs!
Is there any tweak I can try at kernel level to solve this ?
Thanks,
John
