Hello list. Yesterday I enabled polling on my xl0 interface and today when I had rebooted the machine after building and installing a new kernel, I saw something funky in dmesg: (Taken from /var/log/console.log) This is from the same boot: May 15 13:55:19 caulfield kernel: kern.polling.burst_max: May 15 13:55:19 caulfield kernel: 150 May 15 13:55:19 caulfield kernel: -> May 15 13:55:19 caulfield kernel: 10 May 15 13:55:19 caulfield kernel: May 15 13:55:19 caulfield kernel: kern.polling.burst_max: May 15 13:55:19 caulfield kernel: 10 May 15 13:55:19 caulfield kernel: -> May 15 13:55:19 caulfield kernel: 300 then later: May 15 13:55:21 caulfield kernel: kern.polling.burst_max: May 15 13:55:21 caulfield kernel: 300 May 15 13:55:21 caulfield kernel: -> May 15 13:55:21 caulfield kernel: 10 May 15 13:55:21 caulfield kernel: May 15 13:55:21 caulfield kernel: kern.polling.burst_max: May 15 13:55:21 caulfield kernel: 10 May 15 13:55:21 caulfield kernel: -> May 15 13:55:21 caulfield kernel: 300 As you can see the system set's kern.polling.burst_max to 10 from the 150 default value then from 10 to 300 (Wich is the value I put in sysctl.conf) then from 300 to 10 and again from 10 to 300 for the last time. This lookes a bit strange (to me that is). Is this the correct and expected behavoiur ? If so would somebody mind explaing why I can't seem to find any information regarding this on google ;) -- Thordur I. <thib@mi.is> FreeBSD - Unix the way *I* like it.
