I think nullpt sent you off track when he told you to try freebsd-performan= ce. I believe this is an issue for drivers and/or sparc (or maybe current) I think I have a TX2 too. I can try it on my Ultra 5 if more testing is required. PS: I'm cc'ing S=F8ren Schmidt, he's the maintainer of most of the ata driv= ers On 4/6/07, Danny Knaggs <knaggsy2000@googlemail.com> wrote: > Hello all! > > This is first time I've used a mailing list, so bear with me! > > > I've been asked to submit my findings of the ata driver in FreeBSD 6.2 > on my sparc64 and x86 box from bsdforums.org. > > Link to my thread: http://www.bsdforums.org/forums/showthread.php?t=3D486= 82 > > > I've just installed a Promise IDE Controller card (Ultra 133 TX2 - > PDC20269) in my Sun Ultra 10 and have come across a slight snag. > > If I don't put in "hw.ata.ata_dma=3D0" in the loader options I get DMA > timeout errors after it has queried the HDD on the Promise controller. > > I have found a link which someone else has a similar problem (NetBSD on > Alpha) which maybe useful: > http://archive.netbsd.se/?ml=3Dfreebsd-alpha&a=3D2007-02&t=3D3177803 > > Now, after BSD has loaded I can successfully change the DMA mode to > UDMA66 on the HDD without any problems (get ~30MB/s transfer rate, > compared to ~15MB/s when using the on-board controller using "dd").
