Ubuntu Server 6.06.2 was the last server build I could install on that Sun Blade 100 (sparc64). All attempts at getting the IDE subsystem to disable DMA with kernels 2.6.24 and newer failed. As I mentioned above, I tried an exhaustive list of [kernel/IDE] options to disable DMA but was never able t

I'll be happy to test out the Alpha5 build after it is released, but can you tell me precisely what kernel option or options I should provide to disable DMA? I understand ide=nodma is deprecated and may even be removed at this point. And its never been clear exactly what the new option to disable D

Despite all my efforts I could not get DMA disabled on Ubuntu 8.04 using kernel 2.6.24 and a sparc processor. I tried all the options listed above (hda=nodma, the obsolete ide=nodma, ide_core.options=nodma, etc. etc. etc.) and all indications in logs and such were that DMA was disabled as desired,

Good news. Mr. Zolnierkiewicz, maintainer of the Linux kernel IDE subsystem got back to me very quickly, and I quote -- "hdx=nodma" should work fine with kernels >= 2.6.24 -- thank you very much!! I have no experience installing Ubuntu yet. I have some experience with other distributions, but this

I see Hardy Heron Alpha 3 (release 8.04) is bundling kernel 2.6.24. I will contact the author of the above patches to confirm if his patches fix this issue in post 2.6.23.x kernels and will post back here. -- Sparc64 Gutsy Kernel not recognizing ide=nodma https://bugs.launchpad.net/bugs/159152 Yo

Found this post, not sure of its relevance to the Ubuntu kernel http://lkml.org/lkml/2007/3/15/293 "...However the code responsible for manually enabling DMA ("hdparm -d 1") has a bug which results in DMA being erroneously enabled - ide_set_dma() incorrectly passes "0" return value to set_using_d
