I just started playing with 4.0-CURRENT the other day, and I've been using a nice SCSI disk, however, when I connected a couple of Western Digital IDEs, I had a couple strange problems: Same controller in an Asus P5A-A, K6-III 400 MHz @ 100x4... /kernel: ide_pci0: <Acer Aladdin IV/V (M5229) Bus-master IDE controller> at device 15.0 on pci0 wdc0 at 0x1f0-0x1f7 irq 14 flags 0xa0ffa0ff on isa wdc0: unit 0 (wd0): <WDCAC420400D>, 32-bit, multi-block-16 wd0: 19470MB (39876480 sectors), 39560 cyls, 16 heads, 63 S/T, 512 B/S Note there is no DMA on there either... I couldn't get either the 13 or 20 Gig to do DMA, even though I have done it before on -STABLE. The other oddity with early AM yesterday's world & kernel was: wdc0 at port 0x1f0-0x1f7 irq 1 drq 0 flags 0xa0ffa0ff on isa0 wdc0: unit 0 (wd0): <WDC AC420400D>, DMA,32-bit, multi-block-16 wd0: 19470MB (39876480 sectors), 39560 cyls, 16 heads, 63 S/T, 512 B/S wdc0: interrupting at irq 1 What gives with the irq 1? All sorts of things were showing up on irq 1, even though they were actually configured on 14, 15, 5 (for sio2), etc... I thought this was something funky in the bus changes, and may be gone now, I haven't tried the IDE disks again on anything since, but other things (like sio2) are back to normal on the last 5 or 6 builds. Boy these K6-IIIs are FAST... My worldstone is under 1h WITHOUT turning on softupdates, no async mounting, no noatime, no -j, and src and obj are on the same (/usr) partition of one SCSI disk!
