------- Comment #14 from [EMAIL PROTECTED] 2008-11-02 16:06 ------- OK, Quick(ish) update : I have been able to build a kernel that will boot and run smoothly with both bios versions, The only thing I have yet to resolve is an alsa issue which is not relevant to this bug at all and I may be able to solve with an alsa recompile. I have been testing with linux-2.6.27.4 and have had many failures with this machine but right now I am in a workable environment using a build that seems good. Firstly, The first bios version, Which is the original bios version that came preloaded onto the machine, Which this bug is all about. That bios version will only boot and not hang if I do not enable : Local APIC Support on Uniprocessors in a build. However, I do not think that this setting is required at all, The kernel runs very smoothly without it set and does not fail to boot. I know the kernel should not fail to boot with this setting turned on but I would like to know if it is needed at all, I thought lapic was smp related? It seems a strange default option to me but I know little more that it does not work on this m3n. Now, Having created a working build, I then attempted to solve the problem with the massive speed slowdown with the latest bios revision installed. With Local APIC Support on Uniprocessors support built into the build, The system boots and runs very slowly using this bios revision, So disabled. When I turn on highmem support (4gb) The system hangs at udev a bit and then freezes at udev events. That's maybe not acpi but we don't know yet. I should not need to use highmem, The system has 1gb but the kernel spews out a message to turn it on in the dmseg. It's not going on in it's current incarnation. It does'nt play well here. So to sum up so far, I have a working build without Local APIC Support on Uniprocessors and Highmem Support built into the kernel. Please note that I have been using pure vanilla and not patch kludging anything. To follow this bug up with some more useful and meaningful data, I will build two kernels with full debug support, Boot with all the debug turned on and attach the dmesg.log(s) here. One that works and another one with both highmem (4gb) + Local APIC Support on Uniprocessors built in. I will test both bios versions, So 4 dmesg.log attachments. Maybe then it might be clear what's happening here. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
