On a Debian install I recently did, I ended up getting a newer kernel to replace the 2.2.20 kernel I initially installed on the system. But the old kernel remains on the system, and I can boot from it if I enter "LinuxOLD" at the command prompt. The problem is, when I boot using that older kernel, the network doesn't work (it used to work fine prior to updating kernels). The system loads the right driver for the card, but it somehow can't get a dhcp offer. I'm wondering why this is. Anyone have any ideas? Here's an excerpt from a log file that shows the failed dhcp attempt:
