Bug#439012: d-i: network not recognized on Sun nextra x1 / v100 + oops while unloading the wrong module

[Bernd Zeimetz <bernd@bzed.de>]

Package: debian-installer
Severity: important


On Sun v100 and Nextra X1 machines d-i loads the dmfe module first,
which seems to support the ethnernet controller, but in fact it does
not, only tulip does. Unfortunately a modprobe -r dmfe results in an
oops (if the interface is up, it works if you remove the module before
bringing the interface up):

The ethernet controller is:

The network seems to work well with tulip.

Please forward the bug the the appropriate kernel package, too, so the
oops can be fixed.


Thanks,
