Help needed debugging flaky network driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I have a Supermicro X5DP8-G2 board with two onboard Intel gigabit cards (e1000 driver). For some unknown reason, eth0 does not work half of the time when the machine boots - the interface is nominally up, but no traffic flows. (Syslog reports that "link is up" anyway.) If I run
/etc/init.d/network restart
manually, everything is back to normal. This happens under Redhat 9 and Fedora Core 1 and 2. The second interface always works well.


The drivers are written by Intel, so I wrote them, but I don't expect a quick reply. Can anybody suggest some tests that would tell whether it's a hardware problem or a wacky driver issue?

Thanks,
Simon
