random hangs at shutdown

[John Read <john read newnet-marketing de>]

Hi,
since installing networkmanager (0.6.5-98) I have occasional hangs after 
stopping it, as in shutdown. Hal is version 0.5.10)

The hang seems to kill the keyboard and disk interrupts.

Here is the dmesg:
> Feb 21 22:09:30 john NetworkManager: <WARN>  nm_signal_handler(): Caught signal 15, shutting down normally.

then nothing....

I appears to be interaction of the ALSA drivers, but this seems strange.

Can anybody help me?

regards
