Bug#396513: kernel-2.6.18: DHCP fails with stock kernel image, works with roll-my-own kernel
Package: linux-image-2.6.18-1-686
Version: 2.6.18-3
Severity: normal
I have been rolling my own kernels on this machine (Thinkpad A21m,
Debian testing) for a long time, but really don't need to anymore, so I
thought I would install the stock kernel images.
Alas, with the stock images (both linux-image-2.6.17-2-686 and
linux-image-2.6.18-1-686) my network interfaces (both mini-PCI and
PCMCIA) refuse to play with DHCP. If I run tcpdump on the DHCP server
end, I can see the DHCP request coming in from my machine and the
response going out. But tcpdump running locally on the A21m does not see
the response from the server at all.
But, if I boot back into my home-made linux-image-2.6.17-a21m.26,
everything works fine. The only difference is which kernel has been
booted, all other hardware and software configuration is identical.
There are no interesting errors in syslog, the only visible ailment is
that DHCP times out (and tcpdump indicates the response packets are
disappearing into the void somehow).
