I am trying to install Fedora on a PC I built. I had Windows XP running on it for more than a year without any apparent problems. I put a new hard drive in the box and tried Fedora 13 and now Fedora 12. It seems to freeze at random or panic. I suspect hardware or a driver. I've been pulling cards, but it seems to happen regardless of what combination I have in the box. I've tried Gnome, KDE, and now init 3, but it seems to happen with the same frequency. I left it on last night and found these messages on the screen this morning: [<c0409ab5>] apic_timer_interrupt+0x31/0x38 [drm:drm_fb_helper_panic] *ERROR* panic occurred, switching back to text console -------------------[ cut here ]-------------- WARNING: at arch/x86/kernel/smp.c:117 native_smp_send_reschedule+0x23/0x46() Hardware name: TF520-A2+06a/0x01 Modules linked in hwmon_vid sunrpc cpufreq_ondemand powernow_k8 ip6t_REJECT nf_conntrack_ipv6 ip5table_filter ip6_tables ipv6 dm_multipath uinput snd_hda_codec_realtek snd_hda_intel snd_hda_codec snd_hwdep snd_seq snd_seq_device snd_pcm snd_timer ppdev parport_pc snd parport soundcore r8169 snd_page_alloc i2c_nforce2 k8temp mii ata_generic pata_acpi pata_amd nouveau ttm drm_kms_helper drm i2c_algo_bit i2c_core [last uploaded: i2c_dev] Pid: 1517, comm: abrtd Tainted: G D 2.6.32.14-127.fc12.i686.PAE #1 Call Trace: [<c04412dd>] warn_slowpath_common [<c041d044>] ? native_smp_send_reschedule+0x23/0x46 [<c0441306>] warn_slow_path_null+0x12/0x15 [<c041d044>] native_smp_sned_reschedule+0x23/0x46 [<c042dbac>] resched_task_0x5c/0x5f [<c042dc0d>] check_preempt_curr_idle+0x13/0x15 [<c042c1b1>] check_preempt_curr+0x15/0x18 [<c043d85a>] try_to_wake_up+0x14/0x34 [<c043d915>] default_wake_function+0x14/0x34 [<c042d1e7>] __wake_up_comon_0x39/0x61 [<c0433437>] __wake_up+0x23/0x40 [<c0441a09>] printk_tick+0x37/0x3a [<c044e8f5>] update_process_times+0x37/0x48 [<c045df9c>] __run_hrtimer_0xa0/0xef [<c0466dd6>] ? tick_sched_timer_0x0,0xa0 [<c045e1ec>] hrtimer_interrupt_0xe0/0x1d5 [<c041e019>] smp_apic_timer_interrupt_0x68/0x7b [<c0409ab5>] apic_timer_interrupt_0x31/0x38 [<c07a451c>] ? panic+0xc7/0xe7 [<c07a7056>] oops_end+0x97/0xa6 [<c04273f8>] no_context+0x13b/ox145 [<c04274ee>] __bad_area_nosemaphore+0xec/0xf4 [<c07a7f98>] ? do_page_fault+0x0/0x29f [<c0427588>] bad_area_nosemaphore+0x13/0x15 [<c07a88c9>] do_page_fault_0x139/0x29f [<c07a7f98>] ? do_page_fault_0x0/0x29f [<c07a6693>] error_code+0x73/0x78 [<c044e29b>] ? run_timer_softirq+0xd8/0x1f0 [<c04479ca>] __do_softirq_0xb1/0x157 [<c0447aa6>] do_softirq_0x36/0x41 [<c0447b99>] irq_exit_0x2e/0x61 [<c041e01e>] smp_apic_timer_interrupt+0x6d/0x7b [<c0409ab5>] apic_timer_interrupt_0x31/0x38 ---[ end trace 65e050a46d3d088c ]--- I typed these from the screen, so I cannot swear for the accuracy of every character. I've looked for these type of messages in the message log and the /var/log directory, but haven't found them. I don't see any indications of why it freezes in the message log when it does. I looked for core files in a few places but found none. I doubt I've given enough info to pinpoint the source of the problem. So my questions revolve around how to troubleshoot this problem. Where would I look for usable information? What experiments could I try that might point to the source of the problem? Would a core file help? If so, how do I get the system to generate one? How do I figure this one out? Thanks!
