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):
Unable to handle kernel NULL pointer dereference
tsk->{mm,active_mm}->context = 000000000000162f

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,
