I kind solved my problem temporally: I added Hardy repositories and installed only 2.6.24-21-generic. I started with that kernel and my sd* became hd* and all the information/tune-up of hdparm works just fine.
NOW: /dev/hda: Timing cached reads: 918 MB in 2.00 seconds = 458.69 MB/sec Timing buffered disk reads: 98 MB in 3.10 seconds = 31.58 MB/sec And not just that, now my DVD burner in K3B can burn at 4x (before was < 1x). I will look forward to solve my problem in 2.6.27 P.S. I also tried to install kernel 2.6.28 from jaunty repos but the performance was even worst! -- hdparm - cannot set dma on IDE hard drive that works via pata https://bugs.launchpad.net/bugs/110636 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
