 |
|
Running latest gentoo-sources (2.6.14-gentoo-r2). Every now and then the NIC (Intel Gigabit) stops repsonding. Link light is active, and ifconfig shows the same. No errors in syslog. If I restart net.eth0, things usually start working, again. Curiously, if the card is pinged from the switch, it comes back to life (but machine pinging gateway does not have the same effect).
It almost seems that it is going to sleep... but the box is a file server, and there is always activity (NIC has stopped while file copies have been happening).
2 questions:
- Intel has an updated e1000 driver on their site - version 6.2. Should I try it? (version shipped with kernel says 5.x.x from 11/2004)
- Should "Use Rx Polling (NAPI)" be enabled?

I've seen that sort of problem when the switch was set to duplex full 100 and the server was set to auto negotiation. I generally compile the same driver with the NAPI stuff turned on.
You may also want to look at your ACPI setup. Since 2.6.14 you need ACPI to see HT enable chips. Id strip just about everything out of the ACPI config and see if it gets better. I also removed the low latency desktop stuff and set the time slice to 100Mhz rather than the 250Mhz default

I would try it but don't get your hopes up. see here.

The network interface crashes or dissappears. I have a two RAID 5 Arrays with and 82540oem Intel NIC and samba-3.0.14a-r2 and kernel sources 2.6.14-r4 Yes, compilied with NAPI selected in the kernel.
I transferred large files to both an XP and Win2000 machine and both times the network interface dropped. No warning and nothing noted when using ethereal or in the logs to indicate what was going on. There was mention on clarkconnect.com forums that the new driver should fix this but it did not in my case. I rebverted back to my 3com 905 TX and everything worked fine.
I also use a DLink 24 port switch.
For my problem, I found suggestions that Samba should be compiled with
| Code: | | CFLAGS='-D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64' |
However I am not sure how to do this nor how to confirm that it is not already compiled as such.
Be sure to compile support in the kernenl for e1000 as a module and NOT in the kernel. Intel only supplies modules and not kernel patches. The install process from the new drivers will delete the old e1000.ko.
You need to use insmod command with the full path for the module to laod it. Read the README.

| I'm marking this one SOLVED. After upgrading to Intel's latest driver and making kernel changes recommended above, the problme has not returned. |
