After compiling todays 3.2-STABLE, my new kernel cannot boot. It seems that the pci_ide fail on DMA mode. It works after changing to PIO mode. A quick compare on the source tree shows that a new ide_pci code was check in and some changes on the DMA part. The error messages is: ---wd0: DMA failure, DMA status 5<active>---- My Kernel Configuration. I tried both flags on the controller also flags on the disk and get the same result. ---- ##controller wdc0 at isa? port "IO_WD1" bio irq 14 flags 0xb0ffb0ff controller wdc0 at isa? port "IO_WD1" bio irq 14 disk wd0 at wdc0 drive 0 flags 0xb0ff ---Shortened DMESG--------- FreeBSD 3.2-STABLE #4: Thu Jul 22 17:27:07 MYT 1999 FreeBSD/SMP: Multiprocessor motherboard Probing for devices on PCI bus 0: chip0: <Intel 82443GX host to PCI bridge> rev 0x00 on pci0.0.0 chip2: <Intel 82371AB PCI to ISA bridge> rev 0x02 on pci0.18.0 ide_pci0: <Intel PIIX4 Bus-master IDE controller> rev 0x01 on pci0.18.1 wdc0 at 0x1f0-0x1f7 irq 14 on isa wdc0: unit 0 (wd0): <ST34310A>, LBA, DMA, 32-bit, multi-block-16 wd0: 4111MB (8420832 sectors), 524 cyls, 255 heads, 63 S/T, 512 B/S . . hanging root device to wd0s1a wd0: DMA failure, DMA status 5<active> wd0: DMA failure, DMA status 5<active> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
