nx9010
by Alex on Thursday 09/Sep/2004, @02:53
I have the nx9010 dual-boot notebook (WinXP and RedHat FC1). Linux can be run with FC1 native kernel and a custom built with hibernation (sw suspend) and NTFS driver. Can I benefit from your work and install SUSE instead of FC1 to get full hardware support? (will WinXP run with flashed BIOS?) If so could you give some advices?

During development we addressed several general issues together with Suse appearing when installing Linux on a Laptop. Specially ACPI aspects. So others might benefit from that if they are installing Suse on their Laptops. But I can not say, if all hardware will be supported out of the box as we focused on the nx5000 specific components.

Question: what's not supported so far on the nx9010?

>will WinXP run with flashed BIOS?

Yes. The approache here is to offer a BIOS which can be flashed on a Linux machine directly. But it's not a special BIOS version. And right now it's only available for the nx5000. We discuss to offer that for other models as well.

    Hi, I bought a nx9010 last year and managed to get everything I need working in some way. I haven't tested firewire port and pcmcia slots because I don't have any such devices. I and others wrote our experiencies with nx9010 on the page:

    http://freax.be/wiki/index.php/Installing RH9 on a Compaq nx9010 laptop

    Even the hibernate worked for me but my filesystem used to get corrupted from time to time then I decided not to use hibernate. The only one thing that bothers me now is that the two USB 1.1 controllers, ethernet card, video card and modem use the same IRQ 10. Because of this from time to time I see a "too much work for IRQ 10" message in /var/log/messages. Who could I contact to help me with this problem? It would be great if the BIOS let us change the IRQ assigment, but it doesn't.

      Lamarque,

      regarding your IRQ conflict please read that:

      http://www.linux.org/docs/ldp/howto/PCMCIA-HOWTO-5.html

      there is a way to modify how the kernel assigns IRQ resources. And as every time, a solution to configure it within Linux. Good luck!

      >Even the hibernate worked for me but my filesystem used to get corrupted from time to time then I decided not to use hibernate

      As a tester of the nx5000 pre-load I tested this function many times. The distro tested was Suse 9.1. I experienced some problems in the beginning. Suse writes the content of the RAM into the swap partition. So if it happens to be a state, where the RAM content can not be restored for any reason you will lose your swap partition. Slowing up performance. Cleaning swap solves the problem.

      My personal opinion is, there is still more work to do. The current target should be a clear definition within the community how to standardise the implementation of this kind of functions. What's about wake up? Seen many drivers failing here. First thing to fix.

      So go forward. Any feedback is welcome.

      Thomas

        Hi Thomas,

        Thanks for poiting me to the HOWTO. I'll try it.

        When the notebook wakes up everything works fine, even X11, sound card and modem. I haven't tested the ethernet card and the X11 DRI driver after hibernate. I haven't had any crash after waking up. Hibernate was working amazingly for me, if it wasn't for the fact that my Gentoo Linux run fsck once in 21 mount operations I didn't even know that the partition had got corrupted until it was too late. Fortunately I lost only a few KDE config files in my HOME. When I tested hibernate I used kernel 2.4.22, now I use 2.6.7. I'm planning to use hibernate again with 2.6.8.1 or 2.6.9.

    Hi Thomas,

    > Question: what's not supported so far on the nx9010?

    * suspend to RAM doesn't work (P4M supports it as I know (?)),

    * I had to hack ospmd (it takes two events during one power button press, probably for bouth actions - on/off),

    * sound buttons +/-/mute, functional buttons mail/search/...

    some drawbacks for all notebooks running linux (they are not SUSE specific features but must be supported by default, of course they are kernel-related mostly but SUSE as well as others can add required features to kernel being set during installation):

    * hibernation saves kernel with cached data what can take a while, I have to free RAM by memory-eating application before to hibernate,

    * cdrom isn't used in read-ahead mode (it is always spinning even if mp3's are read piece-by-piece),
