--- Comment #7 from Stephan Neuhaus <sten@artdecode.de> ---
Replying to Rodney W. Grimes form comment #5 and comment #6

There are two other machines (one another Debian, one Windows 10) hanging o=
ff
that (very cheap, consumer-grade Netgear) switch for which DHCP works. Also=
, if
I install Debian on the same laptop on the same port on the same switch, DH=
CP
*also* works. So I don't see how STP can be the root of this issue, but I'll
try your suggestions.

I cannot turn off STP or change the way it does STP, since it is not manage=
d.
If you say that putting it next to the server (which hangs off another swit=
ch,
this time managed) doesn't solve the problem, I will try fiddling with the =
STP
parameters on *that* switch and see if it solves things.=20

I must admit though, should that make it work, it would be deeply mysteriou=
s to
me. But I'm willing to concede that my mental model of how these things oug=
ht
to work might be totally wrong :)

As to your other questions: "Are you using the PXE client in the broadcom
BIOS?" I don't even know what that means, TBH. I'm using an old MacBook Pro,
which happens to have a Broadcom NIC in it.

"Are you using any VLAN taggging stuff?" Nope.

"Is this NIC in use as a shared IPMI device?" Nope. This NIC runs in a lapt=
op.

Cheers

Stephan
