    I've been able to reproduce this several times on my Nov 2007 MBP 15". After the SL 10.6.2 update is applied when I reboot I get a wider and larger then normal white Apple on a grey background with a spinning progress indicator telling me the firmware is loading. It then goes to a black screen and NEVER returns.

    If I then boot the MBP in target disk mode, take my old PowerBook 12" and use it to run Disk Utility, Repair on the MBP drive it will find nothing wrong.

    Now if I then restart the MBP is boots with a normal sized while apple, blue screen then everything loads normally. At that point I've used the system for as many as 30 days, or as few as five minutes, reboot and I'm back to the large fat apple logo then a black screen.

    This ONLY happens after 10.6.2 is applied. I've confirmed that 10.6.0 is fine and 10.6.1 is fine. It is most definitely something in 10.6.2, likely a very low level file whose permissions are being corrupted and as soon as the firmware starts initialization it checks for this file prior to even putting up the white apple. I've even cloned my 10.6.2 MBP drive, did a disk repair on both the MBP drive and the firewire clone then after starting up then rebooting on the MBP drive I can't even get to the boot drive select screen to pick the external firewire drive whose filesystem is clean. If I then run Disk Utility, Repair on the MBP drive I can then restart, drive select the external drive and it will restart.

    Is there a hibernation file or something in the 10.6.2 image that might be corrupted or have invalid permissions?

    This is happening to me too, intermittently (of course). After a reboot, the MBP acts like it's at a locked login screen but the monitor (the lcd) is deactivated.

    It happened several weeks ago in the evening. Giving up, I happened to leave it off overnight. When I brought it into our IT guy, I booted it up for him and the "fat apple" magically went away--it booted "normally".

    Fast-forward to now: the "fat apple" has recurred (this always seems to happen when I'm working from home). After trying a few hard reboots I turned it all the way off, took the battery out, disconnected the and let it sit for a while (about 15 minutes). When I restarted it (power supply only, no battery) it didn't do the fat apple thing again, and it seemed happy. "Great", I thought, "I'll just shut it down, put the battery back in, and we're good to go". No such luck. On re-reboot with the battery, it did the fat apple thing again.

    Now I'm trying the 15-minute-no-battery thing again. If anyone has any ideas on how to reproduce this more reliably or even a fix, I'd love to hear it.
