Given that it's showing up in "system", it's likely something interrupt-related. I would first try turning off all power management in the BIOS, and also disabling HPET (High-Precision Event Timer) there if you can. Although it sounds silly, if it's a PS/2-based system, make sure there's a keyboard plugged in. (Some motherboards generate an endless stream of interrupts if there's no keyboard, sometimes it's a BIOS setting for headless operation.)
Poorly-implemented storage (either the hardware or the drivers) can also cause this, but you'd probably see disk I/O in that case. You aren't in the middle of re-mirroring a geom(8) RAID1 set, are you? -Adam Thompson [email protected] > -----Original Message----- > From: Fabian Abplanalp [mailto:[email protected]] > Sent: Saturday, July 31, 2010 15:55 > To: [email protected] > Subject: Re: [pfSense Support] pfSense 2.0 Beta4 on > > Am 31.07.2010 22:52, schrieb Chris Buechler: > > Maybe.
