Package: linux-image-2.6.14-1-686
Version: 2.6.14-2
Severity: important

I have 2.6.12 and 2.6.14 (686 P4) installed on this machine. If I boot back into
2.6.12 DMA is on for /dev/hda. It is off in 2.6.14 and will not enable:

# hdparm -d 1 /dev/hda

/dev/hda:
 setting using_dma to 1 (on)
 HDIO_SET_DMA failed: Operation not permitted
 using_dma    =  0 (off)

This has, as you can imagine, very detrimental effects with ext3
filesystem responsiveness. Ugh!

DMA has worked in every kernel image I have used with this machine,
tracking Sid since summer 2003 with 2.4 and 2.6 kernels. Until now, that
is.

Please let me know what other information you might need. Here is a
hdparm -i just in case that helps.

should have been fixed with dropping the bogus modular-ide.patch.
