some more informations about my dmesg

[Zhang Chris-czhang01]

Sorry guys, the thing really confused me is that I always received this:
 
 
stray irq7 
stray irq7 
stray irq7 
stray irq7 
too many stray irq 7's: not logging anymore 

 
 
what the hell is this?
 
 
last time the dmesg out put which I posted does not include this, but If I run the server for longer time, e.g 2 days, the massage will be included in the dmesg out put.
