Can you take a still photo (snapshot) instead of a motion video of it? I don't even know how to view an avi file. I did a video because I can't photograph all the lines with a photo, because they are larger than my screen and they shows in about 0,5 secs, so it would be impossible with a photocam. What do you mean you don't know how to view an avi file? Unfortunately it seems the only method, as it shows a kernel panic, so I can't login and grab some sort of log it works if I disable ACPI fro the bios, but I need acpi for saving power... flapane@a64:/etc/init.d$ cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 43 model name : AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ stepping : 1 cpu MHz : 2565.551 cache size : 512 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt lm 3dnowext 3dnow pni lahf_lm cmp_legacy bogomips : 5136.42 TLB size : 1024 4K pages clflush size : 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual power management: ts fid vid ttp processor : 1 vendor_id : AuthenticAMD cpu family : 15 model : 43 model name : AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ stepping : 1 cpu MHz : 2565.551 cache size : 512 KB physical id : 0 siblings : 2 core id : 1 cpu cores : 2 fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt lm 3dnowext 3dnow pni lahf_lm cmp_legacy bogomips : 5136.42 TLB size : 1024 4K pages clflush size : 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual power management: ts fid vid ttp I realized that only ACPI SRAT is required to be disabled (http://www.microsoft.com/whdc/system/CEC/SRAT.mspx) in order to boot without any problems. Anyway if I use a 2.6.18 kernel, it still say: powernow-k8: MP systems not supported by PSB BIOS so I don't have any frequency scaling to solve the problem: ACPI_PROCESSOR=y instead of m this is a cpufreq bug, not an ACPI bug. powernow-k8 should be split into two modules -- one that loads in legacy mode and doesn't depend on ACPI in any way, and the other that does depends on ACPI. kconfig changes so that the dependancies are clearer. |
