Hi,

just tried the 2.6.11-mm3 and at boot-time my start scripts try to
enable DMA on my disk (hdparm -m16 -c1 -u1 -X69 /dev/hda).

But while running hdparm, the kernel waits many seconds and gives me
some DMA warnings/errors:

[dmesg output]

That happened also with 2.6.11-rc3 since I thought I should switch away
from my 2.6.8-rc2-mm1 (the best kernel ever ;)).

In kernel config I enabled:
CONFIG_EDD=3Dy

CONFIG_BLK_DEV_IDEDISK=3Dy
CONFIG_IDEDISK_MULTI_MODE=3Dy
CONFIG_BLK_DEV_IDECD=3Dy

CONFIG_BLK_DEV_IDEPCI=3Dy

CONFIG_BLK_DEV_GENERIC=3Dy
CONFIG_BLK_DEV_IDEDMA_PCI=3Dy
CONFIG_IDEDMA_PCI_AUTO=3Dy
CONFIG_BLK_DEV_SIS5513=3Dy

Any hint/clue about that?
