I have a brand new 10 GB IBM UltrStar (DTTA-371010) which is causing
me some pains. If I boot with flags 0x80ff, everything works fine:
wdc0 at port 0x1f0-0x1f7 irq 14 on isa0
wdc0: unit 0 (wd0): <IBM-DTTA-371010>, 32-bit, multi-block-16
wd0: 9641MB (19746720 sectors), 19590 cyls, 16 heads, 63 S/T, 512 B/S
wdc1 at port 0x170-0x177 irq 15 on isa0
wdc1: unit 0 (wd2): <ST32122A>, 32-bit, multi-block-16
wd2: 2014MB (4124736 sectors), 4092 cyls, 16 heads, 63 S/T, 512 B/S
but heavy disk access slows the machine to a crawl, as can be expected
from any device that does heavy PIO. If I try to boot with flags
0xa0ff to enable DMA, however, this is what I get:
wdc0 at port 0x1f0-0x1f7 irq 14 on isa0
wdc0: unit 0 (wd0): <IBM-DTTA-371010>, DMA, 32-bit, multi-block-16
wd0: 9641MB (19746720 sectors), 19590 cyls, 16 heads, 63 S/T, 512 B/S
wd0: ATA INQUIRE valid = 0007, dmamword = 0007, apio = 0003, udma = 0407
wdc1 at port 0x170-0x177 irq 15 on isa0
wdc1: unit 0 (wd2): <ST32122A>, DMA, 32-bit, multi-block-16
wd2: 2014MB (4124736 sectors), 4092 cyls, 16 heads, 63 S/T, 512 B/S
wd2: ATA INQUIRE valid = 0007, dmamword = 0007, apio = 0003, udma = 0407

and a *lot* more of those. Nothing bad seems to hapen (no fs
corruption or anything). In fact, I managed to recompile a kernel
while this was going on.
The Seagate disk (wd2) causes no trouble at all, DMA or no DMA.
The problem occurs in both -STABLE and -CURRENT.
I've attached a complete kernel config and verbose boot log.
