Hi folks,

i update my whole system , and also upgrade my kernel to 2.6.0-test2.
( me was using linux-2.4.19 bevore )

Now me got the problem that me cant activate DMA on my harddrives.
( Me try to active it with the hdparm script on runlevel boot )
Me read a lot of threats here about i but still not find a solution.

Here is the Error-Msg.:

I have the same problem. I scanned the kernel mailing list and notice a few postings about DMA, but did not see this specific problem. I am using the latest version of hdparm 5.4.

What chipset is on your motherboard (lspci might help in this regard)? Look for an entry for that chipset in ATA/ATAPI/MFM/RLL support. If support for your chipset isn't in you won't get DMA despite hdparm trying to turn in on.

Chipset is SIS 745. DMA worked ok with 2.4.19 Gentoo Sources.

Thanx Regor,

me activate the right shipset and now it works.

me wonder a bit cuz me dont need to activate it in the 2.4* kernels.

its easy to find your right shipset with the kde-controll-center
under System->I/O Inputdevices or some like that.

I had the wrong chipset selected. That's what I get for building a kernel when I'm too tired. Changed to SIS and all is fine.

Thanks!
