Public bug reported:

Before upgrading, I could associate with my AP. After upgrading, all I
get is: "ADDRCONF(NETDEV_UP): wlan0: link is not ready"

Here some more detailed infos:

0) lsb_release -rd

Description:	Ubuntu 8.04.1
Release:	8.04

1) uname -a
Now:      Linux tpo-laptop 2.6.24-23-generic #1 SMP Thu Nov 27 18:13:46 UTC 2008 x86_64 GNU/Linux
Before:  Linux tpo-laptop 2.6.24-22-generic #1 SMP (I don't have that at hand) x86_64 GNU/Linux

2) cat /proc/version_signature
Now: Ubuntu 2.6.24-23.46-generic
Before: Ubuntu 2.6.24-22.45-generic

3) dmesg ...

The kernel log is the same after and before the upgrade, except for:
- reordering of events in the log
- timing
- various numbers, such as measured bogomips
- assigned ACPI Interrupt numbers (ACPI: PCI Interrupt 0000:18:00.0[A])
