can you try the "noapic" option at booting? Also, could you try the i586 kernel to see if that one does work (1) I tried the noapic option, but it didn't help any; the system still failed to resume after a suspend-to-ram (2) I tried the i586 kernel with partial success. If I suspended from the console (X not running) then the system resumed OK (though the console messages 'resume warning: bios doesn't restore PCI state properly; resume warning: if resume failed try booting with resume=force' still appeared). However, when I tried suspending while running X, I had problems: when the system came back up the LCD was dark (backlight was off); I tried ctrl-alt-backspace, ctrl-alt-F2, etc, but nothing seemed to happen (hard to tell for sure, since the LCD was completely dark). After several minutes the system spontaneouly did a power-off. (3) I tried the i386 kernel. This kernel appears to work as expected: I can suspend/resume from both the console and X. The same problem persists in the kernels installed by the limbo2 and null betas. If I do a custom config/compite of the kernels sources from these releases, then I get working kernels. I can also compile a working kernel from the kernel.org 2.4.19 release. The problem is apparently in: (1) a RedHat applied kernel patch which is included in all the beta kernels but wasn't included in kernels from preceeding releases or (2) some config setting used by RedHat in compiling the beta kernels (which I do not select when I do a custom config/compile). I experienced exactly the same symptoms on my Thinkpad R31 running RH9 with the 2.4.20-6, 2.4.20-13.9, and 2.4.20-18.9 kernel rpms. A recompile from the latest stable Kernel.org source fixed the issue immediately. In my config file I turned off all APM-related options except CONFIG_APM_DO_ENABLE. there are 2 kernel commandline options that are worth a shot here: apm=no-allow-ints and apm=allow-ints which boot-time override the apm config options. If either one works for your laptop I need the dmidecode output (part of kernel-utils) to make it the default variant for the specific laptop. (We default the the option that works for most laptops and then have a list of others) Tried both allow-ints and no-allow-ints, neither made the slightest difference. I've also compiled a custom kernel from your sources several times, with the same configuration options I used to get a successful apm from the stock kernel. Nothing I've tried gives me a working apm, except switching to the stock kernel source. Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/ |
