Bug Description
Nearly every time I shutdown, the iwlagn driver crashes and shutdown is interrupted. At this point, the only way I can shutdown is by holding down the power button. I can hear a clear 'click' as the computer then powers down. The driver never crashes at any other time even if I'm using wireless for hours at an end. It only occurs when I shutdown.

I'll second this bug--same problem on an HP HDX 9000 series "Dragon" (the HP 20.1" laptop) with Ubuntu 9.04 Final and latest patches as of June 14, 2009. Same issue--screen dumps look much the same as Roshan's, esp. 7th or 8th photo. Nothing in the logs. Found some errors about "hpet" having to reset the counter/timeout to some huge number like 56000, so I changed that by adding the "clocksource= jiffies" to the command-line, not that I think this has anything to do with IWLAGN (which is notorious for causing all sorts of problems on another laptop). Sometimes, I see warnings that the wireless driver (IWLAGN) is in "deep sleep!", but no idea what to do about it. These warnings may or may not be followed by the usual hang.
This problem started happening shortly after applying updates. I do *not* recall seeing this on the fresh install of Ubuntu 9.04. I may rebuild and *NOT* apply updates and see if this makes the issue go away....
