Hi all,
I have one problem with 2.0.0/2.0.1: My EIDE-controller does not longer work as Busmaster-DMA. Yes I have configured:
# # Block devices # CONFIG_BLK_DEV_FD=m CONFIG_BLK_DEV_IDE=y # CONFIG_BLK_DEV_HD_IDE is not set CONFIG_BLK_DEV_IDEDISK=y CONFIG_BLK_DEV_IDECD=m # CONFIG_BLK_DEV_IDETAPE is not set # CONFIG_BLK_DEV_IDEFLOPPY is not set # CONFIG_BLK_DEV_IDESCSI is not set # CONFIG_BLK_DEV_CMD640 is not set # CONFIG_BLK_DEV_RZ1000 is not set CONFIG_BLK_DEV_IDEPCI=y CONFIG_BLK_DEV_IDEDMA=y # CONFIG_BLK_DEV_OFFBOARD is not set CONFIG_IDEDMA_AUTO=y
But the kernel reports at boot:
PIIX: IDE controller on PCI bus 00 dev 08 PIIX: not 100% native mode: will probe irqs later PIIX: neither IDE port enabled (BIOS) hda: IBM-DSOA-21080, ATA DISK drive ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 hda: IBM-DSOA-21080, 1033MB w/96kB Cache, CHS=525/64/63
You see, I have only one controller, the machine is a IBM Thinkpad 760. I am also not able to set dma with hdparm.
The situation with 2.0.36:
ide: i82371 PIIX (Triton) on PCI bus 0 function 9 ide0: BM-DMA at 0xfcf0-0xfcf7 Jan 4 10:00:58 Stinkpad kernel: hda: IBM-DSOA-21080, 1033MB w/96kB Cache, CHS=5 25/64/63, DMA hdb: SANYO CRD-S54P, ATAPI CDROM drive ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
Any hints?
