Hmm.. Information was a bit sparse :)

FreeBSD 4-STABLE. rather fresh sources. There is more than one
system acting up.
They all use IDE, and all have "options ATA_ENABLE_ATAPI_DMA".

Here's the boot dmesg of one of them. It halted about a minute at
startup, with the timeout messages popping up:

atapci0: <Intel PIIX3 ATA controller> port 0xf000-0xf00f at
device 7.1 on pci0
ata0: at 0x1f0 irq 14 on atapci0
ata1: at 0x170 irq 15 on atapci0
