[Bug 527361] [NEW] hotplug interferes with ethernet card

[Rolf Leggewie]

Public bug reported:

it is not exactly clear to me what triggers this, but it's absolutely
reproducible (big Thank You to SynrG from #eeepc for telling me how to
fix this).  Ethernet works fine when booting the ASUS 1001P pinetrail
netbook from one of the live CD, but my legacy karmic system (lucid
kernel!) on HD booted from USB will not show the ethernet device in
lspci or ifconfig unless giving the kernel the boot param
eeepc_laptop.hotplug_disabled=1.  Upstream knows about this and has
committed a fix, although that needs to be broadened to include the
1001P as well, not only the 1005P, it seems.  Please look through
http://bugzilla.kernel.org/show_bug.cgi?id=14570, especially comment 31
and make up your mind what's happening here.  I don't understand it ;-)

I think we should have a fix for this in lucid and possibly in karmic as
well.  These are cheap and popular devices that many newcomers will use
for taking Ubuntu for a test drive.
