Upgrading this server from Fedora Core 4 to 5 went unsmoothly. Sorry if you noticed the long outage.
- The CDs I burned failed the initial media check.
Impossible! A quick check of the Google showed
the magic words to type at the boot prompt:
linux ide=nodma. This caused the media check to pass and allowed us to proceed.
- No surprises for the actual upgrade, except that it was
verrrrry slllow. I assumed this was due to extra careful
error checking, although I have no actual idea. The FC5 install
screens are pretty.
- Finally, we reboot to the upgraded OS. And things look just
swell, except …
- Crap, the network isn't working at all. Output from
ifconfigshows that the system thinks the interface is up, but there are a lot of errors on the transmit and receive sides.
- After dinking around with network configuration tools, I try
unplugging the ethernet connector from the NIC, and plugging it back
in. Hallelulah, things work again! … for about a minute, then
we're back in Suck City.
- Desperate, I'm thinking there's something wrong with the new network
card driver. This is a pretty generic box, a Dell Dimension 4500 with
a Davicom chipset ethernet card (CNET Pro200WL). How bad could that
be? Nevertheless, I scrounge from our local hardware guru a couple
more ethernet cards, one 3Com-based, one Intel-based.
- Surely if anything's gonna work, the 3Com card will. Nope. If
anything, it's worse than the Davicom, because unplugging and plugging
doesn't even make it work for a minute.
- OK, try the Intel card … Yah, we're back now. After about
7 hours of being off the network. Feh.
