See "MESSAGE #1 :: Section #1"
Mark, I know of no cases of "non-DMA-related reports", either.
I am hunting for something to allow someone to save face, with
an apology to you, but no real luck. I have yet to find a flaw.
However IMHO, Linus must still believe that the IDE-DMA has problems or
he would have removed the following.
if [ "$CONFIG_BLK_DEV_IDEPCI" = "y" ]; then
# Either the DMA code is buggy or the DMA hardware is unreliable. FIXME.
bool ' Generic PCI bus-master DMA support' CONFIG_BLK_DEV_IDEDMA
You know that I still back you, and the work that you have done.
I am hunting through the source trying to find anything to question and
confront Linus directly about his lack of forsight in this matter.
OH DAMN, I just spouted HERSEY....So what!!!
SINCE I AM THE ONE WHO SAID IT, DON'T BOTHER "Mark Lord"!!!!!
I will stand alone, if needed to help change the direction of current
kernel thinking.............Good Maintainers are hard to find, and I
personally would like to see your return.
I gather from previous "public" messages to the "linux-kernel" listserv
that the IDE-DRIVER is going to be "Orphaned" soon........ This bites.

Section #1
There are NO current documented cases of disk corruption due to DMA
in the Linux IDE driver. If anyone thinks they know of such a case,
I'd be happy to investigate it .. but all such cases thus far have
been proven bogus.
Section #2
I will not be updating the IDE driver again
until the linux/drivers/block/Config.in file
is restored to its pre-111 state.
