Network Manager wireless functionality is broken with 8688_a2 driver

[Axel Lin]

Create new image with menlow-lpia fsets
Kernel version: 2.6.24-5-menlow-default
click the nm-applet to associate with AP. ( nm-applet UI keep busy and cannot associate with AP )
This isssue happen no matter the AP has encryption key or not.
NOTE: I can use command line to associate with AP and get IP, but with nm-applet it doesn't work.

Below is the messages from /var/log/syslog

Fix Commited today.

[RajiB (raji-linux)]

Fix Commited today, Network Manager was crashing due to unsafe strcmp.

[anagor (anagor)]

Is it possible that the patch broke it off for others?
Or the patch isn't in repositories yet?
This is what I get after the latest updates today:

After which the NetworkManager takes 100% cpu.
Linux-2.6.24.12.13 on x86_64
NetworkManager-0.6.6-0ubuntu2

This happens every time the NetworkManager tries to connect to wireless.
Wired connecions work fine.

Or should I open a new bug-report?

[anagor (anagor)]

Take back my last report :)
It was probably a hal, hal-info bug and not a Networkmanager, since the last update it is again working fine.

Verified in latest network-manager 0.6.5-1moblin3, wireless works well with 8688_a2 driver. Close it.
