When copying directory trees between two IDE drives on the PCI bus, the system really dogs down -- emacs takes 15 seconds to come up when normally it takes 1 -- didn't do that on 3.0-RELEASE. I have these drives configed up for DMA: controller wdc0 at isa? port "IO_WD1" bio irq 14 flags 0xa0ffa0ff disk wd0 at wdc0 drive 0 disk wd1 at wdc0 drive 1 controller wdc1 at isa? port "IO_WD2" bio irq 15 flags 0xa0ffa0ff disk wd2 at wdc1 drive 0 disk wd3 at wdc1 drive 1 These are stock IBM Deskstar drives: wdc0 at 0x1f0-0x1f7 irq 14 flags 0xa0ffa0ff on isa wdc0: unit 0 (wd0): <IBM-DHEA-38451>, DMA, 32-bit, multi-block-16 wd0: 8063MB (16514064 sectors), 16383 cyls, 16 heads, 63 S/T, 512 B/S wdc0: unit 1 (wd1): <IBM-DTTA-350840>, DMA, 32-bit, multi-block-16 wd1: 8063MB (16514064 sectors), 16383 cyls, 16 heads, 63 S/T, 512 B/S Any thoughts?
