(In reply to comment #1) > Additional info: > I also get this problem with the Fedora 15 beta i686 liveCD/USB, but in this > case the screen displays error messages: > Boot with kernel option "vga=1" for 50-line mode and get the entire report. I don't think 50 lines is enough to fit the entire report (btw isn't there an even higher resolution avaliable or a mode with a smaller font?) but here is a longer message with that mode enabled: [ 0.24????] 5a111002 00000001 5f32335f 00000001 00000040 c0a53740 f34a9f94 c0a8d9f1 [ 0.24????] c0a8cb13 c0ad6ab0 f34a9fc4 c0401194 00000000 82bb2757 000008ff 00000040 [ 0.24????] Call Trace: [ 0.24????] [<c0??????>] ? pci_pcbios_init+0xe5/0x234 [ 0.24????] [<c0??????>] ? __pci_mmcfg_init+0x1b1/0xea [ 0.24????] [<c0??????>] pci_arch_init+0x2e/0x63 [ 0.24????] [<c0??????>] ? dmi_id_init+0x266/0x28e [ 0.24????] [<c0??????>] do_one_initcall+0x8c/0x140 [ 0.24????] [<c0??????>] ? pci_arch_init+0x0/0x63 [ 0.24????] [<c0??????>] kernel_init+0x1ec/0x278 [ 0.24????] [<c0??????>] ? kernel_init+0x0/0x278 [ 0.24????] [<c0??????>] kernel_thread_helper+0x6/0x10 [ 0.24????] Code: f8 ff cb 7c 27 ff ff ff ff ff ff ea 53 ff 00 f0 ff ff ff ff ff ff ff ff ff ff ff 5f 33 32 5f 10 00 0f 00 00 01 bd 00 00 00 00 00 [ 0.24????] 00 50 43 49 b0 80 75 17 b0 01 0a db 75 11 bb 00 00 0f 00 b9 [ 0.24????] [<c0??????>] EIP [<c00f0010>] 0xc00f0010 SS:ESP 0068:f34a9f4c [ 0.24????] [<c0??????>] CR2: 000000049435024 [ 0.24????] [<c0??????>] ---[ end trace 44593438a59a9533 ]--- [ 0.24????] [<c0??????>] Kernel panic - not syncing: Attempted to kill init+ [ 0.24????] [<c0??????>] Pid: 1, comm: swapper Tainted: G D 2.6.38.2-9.fc15.i686#1 [ 0.24????] Call Trace: [ 0.24????] [<c0??????>] ? panic+0x5x/0x156 [ 0.24????] [<c0??????>] ? do_exit+0x66/0x61c [ 0.24????] [<c0??????>] ? _raw_spin_unlock_irqrestore+0x13/0x15 [ 0.24????] [<c0??????>] ? kmsg_dump+0x3a/0xb8 [ 0.24????] [<c0??????>] ? oops_end+0xa2/0xa8 [ 0.24????] [<c0??????>] ? no_context+0x128/0x130 [ 0.24????] [<c0??????>] ? __bad_area_nosemaphore+0x11a/0x122 [ 0.24????] [<c0??????>] ? bad_area_nosemaphore+0x17/0x19 [ 0.24????] [<c0??????>] ? do_page_fault+0x159/0x30c [ 0.24????] [<c0??????>] ? _raw_spin_unlock_irqrestore+0x13/0x15 [ 0.24????] [<c0??????>] ? do_softirq+0x8c/0x92 [ 0.24????] [<c0??????>] ? irq_exit+0x4c/0x70 [ 0.24????] [<c0??????>] ? do_IRQ+0x7e/0x92 [ 0.24????] [<c0??????>] ? do_page_fault+0x0/0x30c [ 0.24????] [<c0??????>] ? error_code+0x67/0x6c [ 0.24????] [<c0??????>] ? pci_pcibios_init+0xe5/0x234 [ 0.24????] [<c0??????>] ? __pci_mmcfg_init+0x1b1/0x1ea [ 0.24????] [<c0??????>] ? pci_arch_init+0x2e/0x63 [ 0.24????] [<c0??????>] ? dmi_id_init+0x266/0x28e [ 0.24????] [<c0??????>] ? do_one_initcall+0x8c/0x140 [ 0.24????] [<c0??????>] ? pci_arch_init+0x0/0x63 [ 0.24????] [<c0??????>] ? kernel_init+0x1ec/0x278 [ 0.24????] [<c0??????>] ? kernel_init+0x0/0x278 [ 0.24????] [<c0??????>] ? kernel_thread_helper+0x6/0x10 I have omitted the numbers concealed in the ?????. I can supply these numbers if needed. These numbers are different at each boot time but at least the last 23 messages are the same. Does this still happen with F15 final, or the F16 livecds? These problems disappeared altogether after I RMAed the motherboard and picked up another one. The motherboard I had problems with is the MSI 890FXA-GD70. I switched to the Gigabyte GA-990FXA-UD7 and it now works fine. Since I no longer have the old motherboard in possession I'm unable to reproduce these bugs. Thanks for letting us know. You're welcome. The reason why I RMA:ed the motherboard was not related to the IOMMU feature. The onboard audio chip was defect. Not that I cared about the audio but at least I had a valid reason to use to get rid of it. |
