    PBG4: System Failure message (bluescreen) on start-up after a kernel panic
    Hi everybody -

    I tried searching the threads first, but I'm looking for something pretty specific, so I'll try to be as specific as possible. It's my first post, so I apologize if I'm in the wrong category.

    I have a PowerBook G4. My specs:
    Machine Name: PowerBook G4 15"
    Machine Model: PowerBook5,4
    CPU Type: PowerPC G4 (1.1)
    Number Of CPUs: 1
    CPU Speed: 1.33 GHz
    L2 Cache (per CPU): 512 KB
    Memory: 512 MB
    Bus Speed: 167 MHz
    Boot ROM Version: 4.8.6f0
    Capacity: 74.41 GB
    Available: 63.36 GB (10/5/09)
    OSX Version 10.4.11


    At the moment, it seems to be running fine. I'm on it now. I've verified the disk permissions and nothing seems to be out of place. The problem: over the last few weeks, I've been getting the intermittent kernel panic message. I power down, sometimes it reboots without a problem and I can keep going, if it doesn't I reset the PRAM and it starts up and seems to run fine. The only time I get the kernel panics is when I'm using multiple tabs in Firefox - it will either spontaneously quit or freeze and I'll get the "gray box" telling me to restart my computer. The last time I restarted I got a blue screen with the following message:

    System Faliure: cpu=0; code=0000007 (corrupt skp lists)

    Waiting for remote debugger connection.


    I couldn't move the arrow using the touch pad or cursor keys, it was just frozen. I shut it down, restarted, and it's running like nothing even happened.

    Does anyone have any ideas on what's going on? Preventative maintenance I should be doing? How I can fix or resolve this?

    Thanks for taking the time to read this, I know it's super long...it's just so frustrating!! (...and no worries, of course I've backed-up! )

    Just shooting in the dark here cause I am not really sure what is going on with your PB ...

    Most of the troubleshooting I do is strictly hardware no boot bad hard drives
    bad memory or broken screens. ect.

    have you tried
    restarting pressing command (apple key) and s
    running an fsck -fy to check for errors on your hard drive
    I know you have run permissions but did you check this.

    the other thing that I know will corrupt things is flaky memory as well
    this will show up as kernel panics as well..

    Hopefully there is not a more sever underlying problem with the hardware that
    is just on the brink.

    The other thing to try is try reinstalling firefox you said that it does it when
    you have multiple tabs open but that could also suggest memory or swap
    issues..
    Try this and let us know..

    Thanks for the response, csegeek.

    I did the easiest (in my opinion) first and reinstalled Firefox. After about 30 minutes of normal usage (which, for me, is multiple tabs open) I attempted to open another tab, it stalled in loaded, the gray box of doom appeared and I had to power down.

    I re-started holding down command-S and ran the fsck -fy and received the following information:

    **/dev/r disk 0s3
    **Root file system
    **Checking HFS Plus volume.
    **Checking Catalog file.
    Invalid node structure
    (4, 7335)

    I then restarted without any problems and it seems to be running. The kernel panics are intermittent and I can't figure the problem out. I was thinking of upgrading to OSx10.5 (I don't have the 10.4 install disk - I got the PB used and on its last legs for a song about a year and a half ago and have been fixing it up) and upping the RAM to (2) 512Mb DDR card. I have a brand new battery and a new power adapter. I just replaced the hard drive back in March - I can't see why a brand new hard drive would go so quickly. BUT I don't want to do these things (obviously) if my motherboard or processor is crapping out. Any ideas?

    Really need the disk in order to run a repair disk with Disk Utility instead of fsck.

    The Catalog file basically keeps track of where everything is and the invalid node structure is telling you there are problems.

    First thing I'd do is back up your drive. Then try the 'fsck -fy' as noted above again. If it comes back with 'file system was modifed', keep doing it until it comes back with 'appears to be ok'.

    If it's not repairing - need that disk and/or an erase/install may be in order.

    Thanks, bobtomay. I backed up at the first kernel panic, so at least if I have to erase and re-install, I know I won't "lose" anything. Considering the problem I've been having, would you recommend that I buy an OSx10.4 disk or get the 10.5?

    I really appreciate all the help, guys!!!

    Hi -

    It's been a while since I've posted with the problem, but I've finally got the full resolution so I thought I'd share (in case it helps anyone).

    The first thing I did was upgrade the RAM. I swapped out the (2) 256Mb cards for 512Mb cards and that took care of the kernel panics - no more gray boxes. I still had the invalid node when running an fsck -fy in single user mode.

    I bit the bullet and upgraded my operating system (I went to Leopard). No more invalid nodes.

    Thank you all for your help.

    Amy

    P.S. Since that worked so beautifully and I had the OS, I decided to upgrade my HD afterall, doubled my internal memory to 160GB, so now I have 1GB of RAM and 160GB of memory running 10.5.8 with an internal superdrive on the way...I'm in geek heaven and as close to dancing as I've ever been...

    Glad you got it all sorted out and have an almost new machine for not much money - missed posting back after your last one - that was probably when I was going through and deleting the 50 pages of subscribed threads I had - lol.


    P.S. Just a friendly FYI - your internal memory is doubled for sure, but it is doubled to 1 GB of memory with the two 512 MB sticks you put in. In relation to your hard drive - that wouldn't be called memory, they're just referred to according to the size drive you have. Then taking about what is used vs free on the drive, it's just called simply used 'space' and free 'space'.
