excellent ! hint at a further easy test opportunity:
I used yast to delete the configuration of
Intel 82801I (ICH9 Family) Gigabit Ethernet Controller (on board)
and configured
the rtl8139 card instead. and plugged the network cables into the 8139 outlets.
The yast alone did not do it, the machine needed reboot to show a proper
ifconfig and get actual connection.
the 8139 appears now under eth1, I use the same static address as before.
mpich now appears to work just fine, no crash seen yet after a multiple of
the time needed previously to see a crash and many network transfers.
the 8139 performance is great for fast Ethernet (nominally 100Mb/s) with 170
Mb/s but 6x times lower than we shoot for with the Gb/s network.
The experiment strongly suggests that the PROBLEM is really with the DRIVER
used for the on board Ethernet. I have not found out yet what driver is
used for the intel 82801I . I see two drivers in question e1000 and e1000e
in /lib/modules/2.6.22.5-31-default/kernel/drivers/net/
yast says e1000
Possibly neither is the right driver.
For the previously installed mainboard Intel DG965ss I needed to compile the
driver for (SUSE 10.1 )from the e1000 source provided by Intel.
I found no Ethernet driver source supplied by Intel for current DG33tl .
