How to artificially cause a page fault in linux kernel?

Mac OS Kernel Panic Issue?

• Today my mom was using our Mac OS X computer. The sound, as of recently, has been randomly turning on and off. So we restart the computer, and it fixes it. Today my mom restarted to computer to fix the sound, and it popped up with a kernel panic that looked like this: Previous Shutdown Cause: 3 panic(cpu 2 caller 0x2abf6a): Kernel trap at 0x01457039, type 14=page fault, registers: CR0: 0x8001003b, CR2: 0x00000000, CR3: 0x0010000, CR4: 0x000000660 EAX: 0x9321f629, EBX: 0x00000001, ECX: 0x7c0ebb18, EDX: 0x0000004 CR2: 0x0000000, EBP: 0x7c0ebb28, ESI: 0x0000000, EDI: 0x00000001 EFL: 0x00010246, EIP: 0x01457039, CS: 0x00000008, DS: 0x04b0010 Error code: 0x00000000 Debugger called: <panic> Backtrace (CPU 2), Frame : Return Address (4 potential args on stack) DSMOS has arrived LPAudioDevice[0xdf06600] :: intHardware(0xd120ff00) LPAudioDevice[0xdf06600]::createAudioE… LPAudioEngine[0xde55100]::init() LPAudioEngine::init SUCCEED LPAudioEngine[0xde55100]::initHardware… LPAudioEngine[0xde55100]::createNewAud… LPAudioEngine[0xde55100]{PeformFormatC… 0x8411bb18, 0) LPAudioEngine{{createNewAudioStream SUCCEED LPAudioEngine::initHardware SUCCEED LPAudioDevice::createAudioEngine SUCCEED LPAudioDevice::initHardware SUCCEED ** Device in slot: Slot--1 ** There are a whole bunch of numbers here-- if you need them, let me know.

I tried to reboot the computer in safe mode, but it just went straight to kernel. I also tried resetting the NVRAM and PRAM but yet again it went to kernel. Any suggestions?

• Answer:

  Corrupted OS file or resource seems the most likely cause. It seems to be saying that the hardware is OK, and if you are getting the startup sound the the software is the problem. Startup with your install disk that came with your computer buy holding down the C key with your DVD in the drive. Then use disk utility to see if you can repair the disk and if that fixes the problem.
