Running F8 on a new Dell Vostro 1500 (64 bit) with Intel wireless 3945 abg. Works fine on live CD and initial install on sda. After upgrade and reboot, Network Manager crashes. Automatic crash report was generated by bug reporting tool.
Wireless is down but can still use ethernet cat5
nm-applet crashes on Rawhide LiveCD 20071011 also. Restarting nm-applet from a terminal brings it back and it seems to run fine from that point on.
Yes I am seeing the wired interface being taken down at login with recent Live images spun from i386 rawhide. (IIRC this started happening after test3.)
This should be taken care of in the latest NM build, I believe. Please reopen if you still see the problem with 1:0.7.0-0.3.svn2983.fc8
