My brand new SR Macbook had it's first kernel panics recently (at least I think), all when I tried playing a movie in the DVD player. Is the DVD player to blame? Do I need to re-install it from the Leopard disc? I also not too long ago put 4 GB of ram in, could that be the problem? I wouldn't think so because the DVD player worked fine for a while even after I installed the ram. Here is the kernel panic log: Sat Jan 12 11:04:58 2008 panic(cpu 0 caller 0x00427BC7): "getPhysicalSegment() out of 32b range 0x12c066000, len 0x1000, class IOGeneralMemoryDescriptor"@/SourceCache/xnu/xnu-1228.0.2/iokit/Kernel/IOMemoryDescriptor.cpp:1471 Backtrace, Format - Frame : Return Address (4 potential args on stack) 0x5ade79d8 : 0x12b0e1 (0x455670 0x5ade7a0c 0x133238 0x0) 0x5ade7a28 : 0x427bc7 (0x49897c 0x2c066000 0x1 0x1000) 0x5ade7af8 : 0x42b228 (0x7f75000 0x0 0x0 0x7786d000) 0x5ade7b18 : 0x72bc6c (0x7f75000 0x7786d000 0x0 0x77df308) 0x5ade7b38 : 0x439254 (0x72bb800 0x6a33cb8 0x7851598 0x8) 0x5ade7b78 : 0x439e07 (0x7479a0 0x72bb800 0x6a33cb8 0x8) 0x5ade7bd8 : 0x4379b0 (0x72bb800 0xe 0x5ade7c20 0x0) 0x5ade7cf8 : 0x4390f1 (0x72bb800 0xe 0x0 0x0) 0x5ade7d68 : 0x1898e1 (0x72bb800 0xe 0x6a33cb8 0x8) 0x5ade7db8 : 0x12d165 (0x6a33c90 0x7851570 0x0 0x0) 0x5ade7df8 : 0x126247 (0x6a33c00 0x0 0x34 0x5ade7ee4) 0x5ade7f08 : 0x196afc (0x5ade7f44 0x0 0x0 0x0) 0x5ade7fc8 : 0x19eb34 (0x7d4b960 0x0 0x1a10b5 0x7d4b960) Backtrace terminated-invalid frame pointer 0x14785ac8 Kernel loadable modules in backtrace (with dependencies): com.apple.driver.AppleIntelGMAX3100(5.1.8)@0x6fe000->0x7b6fff dependency: com.apple.iokit.IONDRVSupport(1.5)@0x6f0000 dependency: com.apple.iokit.IOPCIFamily(2.4)@0x60d000 dependency: com.apple.iokit.IOGraphicsFamily(1.5)@0x621000 BSD process name corresponding to current thread: DVD Player Mac OS version: 9B18 Kernel version: Darwin Kernel Version 9.1.0: Wed Oct 31 17:46:22 PDT 2007; root:xnu-1228.0.2~1/RELEASE_I386 System model name: MacBook3,1 (Mac-F22788C8) Thanks everyone!
