I just got the screen that says you need to hold down the power key and restart your computer. Anyone know why? I'm running tiger. I had about 12% battery left and I am "borrowing" my neighbors internet because mine is down right now (I'm a broke college student). I had about 1-3 bars of internet but those go in and out and fluctuate often. I've noticed my computer seems to lag because of that, I've had a lot more applications crashing. I was watching a youtube video in firefox when it happened. Not even HD just standard. And I had one other tab open to a thread in one of these forums that I forgot about. I wasn't switching back and forth between tabs or anything. I also had caffeine open so that the computer would not fall asleep. Here's the message I got when I restarted: panic(cpu 0 caller 0x0035D60C): mbuf address out of range 0xaa7fba4 Backtrace, Format - Frame : Return Address (4 potential args on stack) 0x13ecbab8 : 0x128d0d (0x3cc65c 0x13ecbadc 0x131f95 0x0) 0x13ecbaf8 : 0x35d60c (0x3ed584 0xaa7fba4 0x13ecbb68 0x14185d) 0x13ecbb18 : 0x23c153 (0x1 0x2 0x13ecbd18 0x5e3e8c) 0x13ecbc28 : 0x23acfb (0x3dcb920 0x899f8f8d 0x899f9535 0x6e01a8c0) 0x13ecbe08 : 0x22f8b2 (0x25b4f600 0x14 0x13ecbe58 0x1a1ee8) 0x13ecbe48 : 0x231313 (0x25b4f600 0x14 0x6 0x0) 0x13ecbf58 : 0x21ea88 (0x25b4f600 0x25b4f600 0x44707c 0x1a3736) 0x13ecbf98 : 0x20529e (0x2d6ca04 0x25b4f600 0x25c2a812 0x1) 0x13ecbfc8 : 0x19b21c (0x0 0x0 0x10 0x30cb0e0) Backtrace terminated-invalid frame pointer 0x0 Kernel version: Darwin Kernel Version 8.11.1: Wed Oct 10 18:23:28 PDT 2007; root:xnu-792.25.20~1/RELEASE_I386 Model: MacBook2,1, BootROM MB21.00A5.B07, 2 processors, Intel Core 2 Duo, 2 GHz, 1 GB Graphics: Intel GMA 950, GMA 950, Built-In, spdisplays_integrated_vram Memory Module: BANK 0/DIMM0, 512 MB, DDR2 SDRAM, 667 MHz Memory Module: BANK 1/DIMM1, 512 MB, DDR2 SDRAM, 667 MHz AirPort: spairport_wireless_card_type_airport_extreme (0x168C, 0x87), 1.4.4 Bluetooth: Version 1.9.5f4, 2 service, 0 devices, 1 incoming serial ports Network Service: AirPort, AirPort, en1 Serial ATA Device: Hitachi HTS543216L9A300, 149.05 GB Parallel ATA Device: MATSHITACD-RW CW-8221 USB Device: Built-in iSight, Micron, Up to 480 Mb/sec, 500 mA USB Device: IR Receiver, Apple Computer, Inc., Up to 12 Mb/sec, 500 mA USB Device: Bluetooth USB Host Controller, Apple, Inc., Up to 12 Mb/sec, 500 mA USB Device: Apple Internal Keyboard / Trackpad, Apple Computer, Up to 12 Mb/sec, 500 mA Mean anything to anyone?
