Bug#508151: linux-image-2.6.26-1-sparc64: soft lockup when trying to bring up eth1
I have a Sun Netra T1 200 with two ethernet ports on a sungem card.
eth0 has no cable connected, eth1 is connected to a regular 100BaseT
When I boot up the box, I get flooded with
eth0: switching to forced 100bt
eth0: switching to forced 10bt
But the box is stable and I can do everything with it.
However, when I try to "ifup eth1" (both interfaces have no "auto" lines
the box gets stuck, prints a soft-lockup and isn't responsible anymore.
(sorry for the broken lines, my serial console is somehow borked)
This bug is opened upstream:
And at ubuntu: https://bugs.launchpad.net/linux/+bug/234304/
It does not happen with Etch's 2.6.18, but is still present in
Bisecting linux-2.6, it looks like the following commit is the bad one:

[NET]: Make NAPI polling independent of struct net_device objects.
However, I wasn't able to properly revert it to test the bug.
Hope some of you sparc guys have some idea how to fix that, as this is a
imho bad regression from Etch.
