Product: kernel-2.4.19.16mdk
Component: kernel-2.4.19.16mdk
Summary: Intel ICH4 based Motherboards-- sound and IDE DMA do not
work
Version: 1-1mdk
Platform: PC
OS/Version: All
Status: NEW
Severity: major
Priority: P2
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
The intel motherboards with the ICH4 controller have severe problems with kernel
2.4.19.16mdk.
a) On boot up, the message
PCI: Device 00:1f.1 not available because of resource collisions
The relevant sections from dmesg are
....
The first reference to 00:1f.1
PCI: PCI BIOS revision 2.10 entry at 0xf0031, last bus=2
PCI: Using configuration type 1
PCI: Probing PCI hardware
PCI: Using IRQ router PIIX [8086/24c0] at 00:1f.0
PCI: Found IRQ 9 for device 00:1f.1
PCI: Sharing IRQ 9 with 00:1d.2

ICH4: IDE controller on PCI bus 00 dev f9
PCI: Device 00:1f.1 not available because of resource collisions
ICH4: (ide_setup_pci_device:) Could not enable device.

b) trying to start up dma does not work.
hdparm /dev/hda
/dev/hda:
multcount = 16 (on)
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 1868/255/63, sectors = 30015216, start = 0
]>hdparm -d1 /dev/hda
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
The disks are very slow.
c) Sound does not work. The standare oss drivers do not load at all. -- error
that the codec cannot be intialised. The alsa drivers load fine, but again
no sound. (again using the onboard sound ICH4 sound card)
------- Additional Comments From [EMAIL PROTECTED] 2002-12-02 21:39 -------
The new 2.4.20-0.6mdk kernel from cooker appears to solve these problems.The error
message ( resource conflict) still remains, but according to Alan Cox, the kernel
actually fixes the incomplete Bios setup which apparently triggers this message. Both
sound (under oss, but apparently not under ALSA) and the ide bus seems to work (
kernel compiles are 20 min or so, rather than 12 hours, hdparm reports 300MB/s rate
from cache, and 16MB/s rate from disk read, rather than 80 and 2.)
