Cardbus/3c575 hotplugging dysfunctional in 2.5.72

[mikpe]

With 2.5.72, my laptop with a Cardbus 3c575 NIC and RH9 user-space
(hotplug-2002_04_01-17 and kernel-pcmcia-cs-3.1.31-13) no longer
brings eth0 up automatically on insertion of the NIC. cardmgr
_is_ running. A manual ifup eth0 brings it up however.

This all worked fine up to 2.5.71.

The only relevant diff in the dmesg logs is:
--- dmesg-2.5.71	2003-06-18 14:17:44.000000000 +0200
+++ dmesg-2.5.72	2003-06-18 14:17:52.000000000 +0200
@@ -3,4 +3,3 @@
 05:00.0: 3Com PCI 3c575 Boomerang CardBus at 0x1800. Vers LK1.1.19
 PCI: Setting latency timer of device 05:00.0 to 64
 eth0: Dropping NETIF_F_SG since no checksum feature.
-eth0: Setting full-duplex based on MII #0 link partner capability of 01e1.

2.5.72 discovers the device, the 100Mbps link led on the NIC
lights up, but nothing further happens.

Any ideas?

Oh crap. It was Stephen Hemminger's patch
http://marc.theaimsgroup.com/?l=linux-kernel&m=105554780621594&w=2
which changes the net device hotplug protocol. The fix -- update
/etc/hotplug/net.agent -- is described in the above page.

Yet another item for the "from 2.4 to 2.5" check list.
