 Here's the dmesg output from several different builds, all of which 
 exhibited the same problem. dmesg.txt is from the -stable with generic 
 kernel build #59, newly reinstalled on my machine today. The other two are 
 from -current kernel builds 221 and 231 respectively. I tried a build last 
 weekend as well, which also exhibited the problem, but it was too unstable 
 in general; causing crashes every few hours so I reinstalled -stable #59 
 today. As I mentioned in the sendbug message, I reported this problem in 
 December on the misc mailing list but it didn't get resolved, nor have I 
 heard from the individuals that said that they'd look into the matter.
