Greetings! |

I've recently updated from kernel 2.6.20 to 2.6.24 a little used |
| 4 |
machine. The new kernel is working quite well. However hdparm isn't |
| 5 |
happy. |
| 6 |
|
| 7 |
Running either "hdparm -d0 /dev/hda" or "hdparm -d1 /dev/hda" gives a |
| 8 |
"HDIO_SET_DMA failed: Operation not permitted" error. Using the same |
| 9 |
config for 2.6.25 gives the same result as 2.6.24. |
| 10 |
|
| 11 |
Here are the DMA related options that are enabled: |
| 12 |
|
| 13 |
OLD (2.6.20): |
| 14 |
|
| 15 |
CONFIG_BLK_DEV_IDEDMA=y |
| 16 |
CONFIG_BLK_DEV_IDEDMA_PCI=y |
| 17 |
CONFIG_GENERIC_ISA_DMA=y |
| 18 |
CONFIG_IDEDMA_AUTO=y |
| 19 |
CONFIG_IDEDMA_PCI_AUTO=y |
| 20 |
CONFIG_ISA_DMA_API=y |
| 21 |
|
| 22 |
|
| 23 |
NEW (2.6.24 and 2.6.25): |
| 24 |
CONFIG_BLK_DEV_IDEDMA=y |
| 25 |
CONFIG_BLK_DEV_IDEDMA_PCI=y |
| 26 |
CONFIG_GENERIC_ISA_DMA=y |
| 27 |
CONFIG_HAS_DMA=y |
| 28 |
CONFIG_ISA_DMA_API=y |
| 29 |
CONFIG_SCSI_DMA=y |
| 30 |
CONFIG_ZONE_DMA=y |
| 31 |
CONFIG_ZONE_DMA_FLAG=1 |
| 32 |
|
| 33 |
Can anybody tell me what I've missed? |
| 34 |

Thanks. |
