This is a followup "It works now and this is what I did" message in relation to this issue so it ends up archived and is searchable. The problem below hasn't recurred for almost 7 days. I did the following (obvious things): 1) Updated to latest version of -stable 2) Turned off APM on the second motherboard (I believe it was off in the original motherboard which also had the problem, but I am not 100% sure). 3) Updated flash bios. It had P03 and I updated it to P07. 4) Did a once-through in bios and insured everything was set correctly. I don't think I changed anything. I did ensure PnP os was turned off and reset the config stuff. 5) Disabled sound on motherboard. 6) Left "old" fxp0 driver in the kernel (non-mii) Several people indicated that this might be caused also by a Denial of Service attack of some sort. I saw nothing in netstat to indicate this, HOWEVER, I have no empirical evidence one way or another other than it went away when I did the above items, and did not recur afterwards. Will follow up if it reoccurs. On Thu, 24 May 2001, Forrest W. Christian wrote: > Date: Thu, 24 May 2001 10:33:57 -0600 (MDT) > From: Forrest W.
