I'm seeing similar behaviour on a HP DL360g4 running 6.1-RELEASE and  
a GENERIC kernel. It had similar problems with 5.4. I have 2 other  
similar machines running 6.1, which don't record these errors,  
however they never see any sustained throughput whereas this machine

Fortunately all it seems to be doing is bothering my log files. I'm  
taking an interest as I have two important production machines using  
the bge driver both about to be upgraded from 5.3R to 6.1R. I've just  
grepped the logs on those machines and they both have a sprinkling of  
timeouts (5 over 18 months on one quite heavily trafficked webserver,  
the other which continously serves http downloads is clean apart from  
1 24hour period when it was having 200GB of files uploaded to it). My  
concern is that upgrading to 6.1 or 6.2 and then enabling device  
polling is going to make the issue worse.

I'm happy to supply more info.
