  • Abit KN9 Ultra problems

    Hi, after reading your (rather glowing) review of the Abit KN9 Ultra motherboard, I figured it would be a good choice for a low-cost Linux box I wanted to build. However, I've had no end of problems trying to get it to run. I get kernel oopses and panics at seemingly random times(although usually involving disk I/O), and I can't figure out why. The memory appears to be fine; I've run memtest86 about 6 times and no errors turned up. I've tried swapping video cards, reseating the RAM and CPU, trying different hard drives, nothing seems to work. I even tried downgrading the BIOS to the version used in the review.

    Were there any weird options that you had to pass to the kernel to get it to boot/run properly?

    Other parts I used:
    AMD Athlon64 3800+ (Orleans)
    Western Digital 7200RPM SATA Hard drive
    Radeon 7000 PCI graphics card(this isn't a gaming machine ), later replaced with an ancient ATI Rage PCI card
    1GB(2x512MB) DDR2-800 RAM

    Any tips or pointers would be appreciated.

    What distribution are you using? It had worked with Ubuntu Edgy Eft, Ubuntu Feisty Fawn Daily, Fedora Core 6, etc... both i386 and x86_64.

      I've tried Gentoo(amd64 & x86), Fedora(amd64), OpenSUSE(amd64), Ubuntu(x86 & amd64), and an old version of knoppix(x86), and all of them have been flaky, although ubuntu and knoppix seemed to last the longest.

        Where is Fedora 6 AMD64 stopping?

          Right now it's frozen right after the "You will need Fedora Core Discs 1&2 " dialog, and anaconda is hogging the CPU. The first time I tried it, it crashed right as anaconda started.

            Have you tried clearing your CMOS and using all the stop BIOS options?

              If by "stop" you mean "stock", yes, I have. Several times. I really don't want to RMA any of the parts but it looks like I might have to... the hard part is going to be figuring out which part is bad. :P

                Oops yeah meant stock

                A Fedora Core 6 LiveCD was released yesterday -- you may want to try that to see if it will load and would help narrow down the troubled part.

                  OK, I'm pretty sure it's the processor that's bad. GCC segfaults and/or causes the kernel to panic when compiling the kernel, and the mprime torture test fails after about 20 seconds. I've tried a different power supply with the same results.

                  I'm going to try to get an RMA for it tomorrow.

                    Try with BIOS 1.3.
                    Since 1.4 there are some APIC problems, read here:http://forum.abit-usa.com/showthread.php?t=112136
