Hi :) I have an A104 and wondered if other owners could confirm the strange behaviour I'm seeing.. it's best seen on an idle system, thus eliminating asterisk or other factors..
Very simply, just let 'vmstat 1' run for a few minutes and watch the output, specifically the 'sy' column... On the 2.4G Xeon machine I'm using, the system CPU usage sits very low for a minute or two, and then spikes up to 100 for a few seconds, before tailing off again - this happens all the time :( Interestingly, the 'load average' as reported with 'w' always stays at zero even with this high 'system load'... I moved the card to another PCI slot (and bus) and get the same thing, but now much more frequently, but for a much shorter length of time... Now bringing Asterisk into the picture, I can't use Monitor() because once I get even 5 simultaneous recordings, the real 'load average' on the machine spikes up to 2 and greater, and calls become stuttered as the machine fails to keep up with whatever it's doing.. The machine is SCSI, with a decent LSI Logic onboard controller and fast disks - so it's nothing to do with enabling DMA - hdparm shows 70MB/sec with minimal load increase. Can anyone confirm this behaviour?
