Thanks Onno & Nick
Nick, I was under the impression that most Intel kernel modules are
blob-free but I took a look on both the the affected debian system and the
working (K)ubuntu system and the results are interesting, but not yet
conclusive or obvious.
Onno, your suggestion is sound but sounds very time consuming, of which
time is not something I have in abundance.
I'm not sure if its worth noting, but this debian installation is very
minimal *without* the "standard system utilities" and only SSH was selected
at tasksel --new-install before I installed the packages I wanted to
build this system.
Is it possible that not buildng this with standard system utilities is the
probem?
Furthermore, the issue doesn't just affect this NIC/kernel module either,
it also seems to affect the following, which is currently installed in a
working ubuntu system with the e1000e kernel module, which I can reference
for differential analysis purposes (firmware, code, dependencies etc) if
and as required.
Intel 82571EB Gigabit Ethernet Controller
Thank you all for your assistance, support and advice so far!
