    Since a few weeks I'm having regular kernel panics. It happens a few times a weeks (sometimes several times in a day), I have a hard time finding out why. thanks if you read my rather long post.
    Here is my setup:
    -Macbook Pro 13" 2,4 Ghz (last model), SSD 120 Go (vertex 3) in HD Bay, original HD in superdrive caddy, 8 Go RAM
    (I bought it like this:
    http://www.macway.com/fr/product/23...-8-go-ssd-120-go-dd-500-go-5400-trmin-mw.html
    )
    -snow leopard 10.6.8 (cloned from white macbook 2007)
    Typical desktop setup (might be related):
    -a 23" screen plugged via HDMI, with SwitchResX to deal with different screens configurations
    -a USB kvm with keyboard an mice
    -a MOTU ultralite sound interface via Firewire, self powered, and sometimes a FW disk chained to it.
    -each time I have a kernel panic I launch disk utility on the system from another disk which find a few errors.

    Each time the kernel panic occured it was in a different situation, but I have a suspicion it might be linked to either the screen management, either the
    sound interface and/or the daisy chain link to the external drive. It is really not happening that often that it it's easy to test each element one by one.
    It happend twice while watching online videos (maybe while switching to fullscreen, but not sure), with firefox, once when switched on the firewire drive while streaming sound through the motu (from ableton live), once again yesterday while doing a few downloads, copying a big file, and when I switched a game fullscreen. These all might be details but you never know.
    I also a have a cpu running pretty hot (80-90° when the integrated gpu is in medium use, 91° whith full cpu usage).
    I have had this computer working fine since january so I doubt this is to do with the cloning of leopard. I suspect something to do with graphics, screen or firewire (there are a lot of cables on my desktop), maybe a hardware problem within the cables, but that's just an hunch.
    Also I had a few bugs with the sound interface, and on my old system I had sometimes no sound at all.
    This is a machine I use for live music performances, and I had a few stressful experiences with live music and computers already (specially how I rely on it), so I'd really like to find out where it comes from.
    I can provide the kernel panic logs if somebody has an idea on how to interpret those.
    also it would be a pain to have to make a clean install of snow leopard on this machine (since I can't really, need to go through either cloning or install from another computer). will do it if necessary though.
    I have no timemachine backup but really considers getting one to see if it's related to software.
    any input welcome. thanks.

    thought the ram was a too convenient culprit (had to change at least one faulty ram module on pretty much every computer I owned). ran "memtest" twice , got a kernel panic on the second pass (near the end). need to confirm this with further testing and nothing plugged in. after a goodnight sleep.
    tried the apple self test, holding "D" at startup but absolutely nothing happened. maybe I need the lion recovery partition to do this.
    still welcome any input on this.

    ok I ran memtest again, whitout nothing plugged in, from different systems, and the test itself is okay but the kernel panic occurs when memtest tries to exit or when I trigger the exit (ctrl C). weird stuff, but is it definitely pointing to a memory issue?

    yep.
    Will try the different ram modules separately (when I get the right f$$$ing screwdriver). hope it's a ram problem and not a more annoying hardware issue.
    here goes:

    Are the RAM modules clean? I use gloves, if possible.

    FireWire uses DMA, so it looks like a RAM problem.

    Intel HD Graphics uses the main RAM as Video RAM (VRAM). Looks like a RAM problem.

    thanks for looking into it, I should have checked this first, this is a problem I had with every computer I owned (last time got the beeps of death at boot)
    I will try to confirm this as soon as I can borrow the tiny screwdriver needed from a friend. I also have the original 2*2 GBs ram lying around.
    What do you mean are they clean? you think I could try blowing on it like we did on those oldschool game console cartridge?
    should I unplug the battery to switch the ram?
    also can I put one 4 GBs and one 2 GBs module at the same time while I wait for a replacement?

    ok, had to buy a screwdriver (almost thought I "screwed" a screw), but one module alone gives me kernel panic, the other doesn't, so here I have it, back to the store (wondering if I really need 8 GBs RAM), onto the next problem, thanks folks.
