Description of problem: I have a Dell C521 with Athlon X2 3800+ and nVidia C51 chipset. I have booted with 2.6.18-1.2798.fc6, 1.2849 and rebuilt 1.2849. All kernels will boot with no arguments but provide only 1 CPU core. With no arguments the timer (IRQ0) is "XT-PIC". If I booted 1.2798 with "acpi=off", I would get both cores, but the mouse would lock up. The mouse lock up is a big problem with the Dell Athlon Dimension boxes (see bugzilla,kernel.org BUG #7397). There is some issue with the mouse (USB issue w/ nvidia ?). I am reporting a minor other issue. With 1.2849, booting with "acpi=off" causes the boot to hang. I downloaded source and recompiled with kernel with CONFIG_X86_APIC_AUTO not set. I can not boot both cores. Version-Release number of selected component (if applicable): kernel-2.6.18-1.2849.fc6 How reproducible: boot with "acpi=off" Steps to Reproduce: 1. 2. 3. Actual results: will not boot Expected results: boot with multiple CPUs Additional info: If I rebuild the kernel with CONFIG_X86_APIC not set, then I can boot with "apic=off". This option somehow messes up the boot process on Dell C521.
Created attachment 141575 [details] tar file with relevant dmesg and /proc/interrupts files
The last sentence of my description should have read: "I can now boot both cores." [with modified 1.2849]
I found that if I use "acpi=off" and "lapic" with 1.2849 then the boot succeeds.
(This is a mass-update to all current FC6 kernel bugs in NEW state) Hello, I'm reviewing this bug list as part of the kernel bug triage project, an attempt to isolate current bugs in the Fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug, however this version of Fedora is no longer maintained. Please attempt to reproduce this bug with a current version of Fedora (presently Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a few days if there is no further information lodged. Thanks for using Fedora!
Per the previous comment in this bug, I am closing it as INSUFFICIENT_DATA, since no information has been lodged for over 30 days. Please re-open this bug or file a new one if you can provide the requested data, and thanks for filing the original report!
