But it is usually important to add all the relevant information you have available. Exact kernel version, any special config option you used when compiling the kernel, any error message printed during boot, the last message printed before the system froze, etc... It is hard to help debugging a problem without information. Regards, Luis -- [ Luis Claudio R.

OK , I don't have laptop here, next weekend I can send dmesg , lspci dmidecode etc . I test with Fedora-10-Live-Beta-x86_64, kernel-2.6.27-0.352.rc7.git1.fc10 and a Fedora 9 updated kernel with kernel kernel-2.6.26.5-45.fc9.i686 test with others kernel from Mandriva . but my initial question is: where I can find more documentation , for trying debug this problem ? debug boot parameters , etc Thanks, > > Regards, > Luis -- Sérgio M.
