Per my conversation with the originator, we need the following information in order to troubleshoot this laptop problem. Please append it to this bugzilla. uname -a > kernel level ("latest patches" is not adequate information since this changes often) lspci -vv > lspci.vv lspci -n > lspci.n lsmod > lsmod.out cat /var/log/messages > messages cat /var/log/dmesg > dmesg This will give Engineering an understanding of your box but is not a guarantee that we can fix it so our code is compatible with it. Many laptops use special chips to save power that cause problems. Though this happens most often with video chips, it can also be a problem with other functions such as USB2, sound, NICs, onboard modems, firewire and wireless. Recently, with the extreme competitiveness of hardware pricing, some vendors have been using really cheap CD-ROMS that we can't get to work with Linux. I've also seen some systems run OK under windows but die under the more demanding requirements LInux can put on their junk hardware. The best way to insure that the machine you have is compatible with Red Hat Linux is to look on the Red Hat web site for the hardware compatibility list (search on hcl). Many of our major partners either certify their hardware and have Red Hat post the results, or they pay Red Hat to certify their hardware. Though this process focuses on servers there are some workstations, desktops and laptops certified on this site. The "compatible" list offers people a chance to list their favorite NICs and other adapters. The other thing that can complicate matters is that vendors sometimes tweak their chips during their life cycle and assign new revision codes which are detected with the above lspci commands. Sometimes these "tweaks" make a once valid certification become invalid. Doing a google search (www.google.com/linux) on the Internet can also be quite helpful. Use your labtop model as a search argument and see what turns up. When I bought my first laptop several years ago, I had to search the Internet for a video driver and download it from a French website with its French docs to get the laptop working. It's a good thing I studied French in high school otherwise the instructions would have been impossible to understand. Red Hat can not guarantee that every piece of hardware will be supported by RH Linux. Vendors will always test with the latest version of Windows because they know if it doesn't run that propretary OS, they won't be able to sell their hardware but many are only beginning to see the light and test their hardware on Linux. Note also that Red Hat does not have the time to solicite information from vendors regarding specific hardware nor to we buy such hardware to test it. Several of our partners loan us the equipment they feel their customers will purchase and want to run Linux on. You might want to write your laptop manufacturer and ask them if they plan to certify it for use with Linux. They might begin to see the light.... there is a "nousb" kernel option (type "a" in grub to add it) that should disable any usb use so that it becomes possible to diagnose this further |
