Over 60% of one core is used responding to interrupts. The machine also hangs frequently. irq19 is shared by atapci1, atapci2, fwohci0 and uhci4... the consensus response to my last question was that "it's probably the ata driver". Today I tried building and booting a GENERIC current kernel and got another piece of information. The freebsd-current GENERIC kernel does not boot; shortly after probing the drives it says "Cannot setup DMA" several times on the console and hangs. This machine is an Asus P5Q-E... I believe it has two ATA controllers: a Marvell 88SE6121 and a Silicon Image SIL5723. Is one of these chipsets generating interrupts that the driver doesn't understand and/or properly dismiss? Can it be put into a legacy mode that works? This machine has problems in 7.0, 7.1 and current... I'm running out of ideas. Thx, Scott
