- Dell Studio 1558 with Intel CPU in i386 mode and four CPUs.
+ 3) What is expected to happen with my Dell Studio 1558 is that when
+ using wifi hotspots away from home, it works without problem.
  
- Most of the time wifi works perfectly. Occasionally, when using wifi
- hotspots away from home, the system never makes a connection. Usually I
- see similar stack traces in the syslog, but the attached extract is the
- only example I have to hand.
+ 4) What happens instead is that the the system never makes a connection, and 
there is a crash in syslog:

- The system is resuming after suspend, but I do not believe that aspect
- is relevant. I have seen similar crashes after powering on, and (to
- repeat myself) in more than one hot spot. I suspect there is an edge
- case in negotiating with some wifi routers that is not handled properly.
- (Perhaps I am prejudiced, but I get the feeling that the problem routers
- are in iPhone-friendly environments).
+ The system is resuming after suspend. However, I have seen similar
+ crashes after simply powering on, and in more than one hot spot.
