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=y
CONFIG_BLK_DEV_IDEDISK=y
CONFIG_IDEDISK_MULTI_MODE=y
CONFIG_BLK_DEV_IDECD=y
CONFIG_BLK_DEV_IDEPCI=y
CONFIG_IDEPCI_SHARE_IRQ=y
CONFIG_BLK_DEV_GENERIC=y
CONFIG_BLK_DEV_IDEDMA_PCI=y
CONFIG_IDEDMA_PCI_AUTO=y
CONFIG_BLK_DEV_SIS5513=y

Any hint/clue about that?
