It gets as far as listing the timecounter values, and then resets twa0 every couple of minutes forever. The box is 2x3.2GHz Xeons, 4GB RAM, SuperMicro X6DH8-XG2 motherboard with 2 integrated em interfaces, 2 x quad-port em cards, 3ware 9000 controller. 3ware probes thusly: twa0: <3ware 9000 series Storage Controller> port 0x2000-0x20ff mem 0xdf800000-0 xdfffffff,0xdd200000-0xdd2000ff irq 28 at device 3.0 on pci2 twa0: 4 ports, Firmware FE9X 2.04.00.005, BIOS BE9X 2.03.01.047 I'm posting this here because everything works beautifully until we turn on polling. We're setting HZ=1000 and turning off SMP in the polling kernel config. Anyone have any experience with this?
