after installing mountain lion 10.8.2 from lion, my iMac crash every time I start it up. I've activated filevault. with filevault, you need to enter the password before OS starts. after I enter my password login, a kernel panic message comes on monitor and system reboot. after this reboot, it starts and goes on normally, without kernel panic.

iMac late 2009, with nvidia g9400 and 8 g of ram.

any suggestions?

    Please post the complete Kernel Panic log, we can sometimes tell from the log what is causing your KP. Please read How to log a kernel panic for instructions.

    Hi Andrea,

     

    Does the same happen if you Safe Boot from the HD, (holding Shift key down at bootup)?

     

    Also, Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.

    This sounds like the exact same problem I reported in this thread: https://discussions.apple.com/thread/4481790?start=0&tstart=0

     

    There seems to be a kernel bug in ML when using FV2, but it only affects some people. I'm hoping enough people with AppleCare report it so that it gets fixed in a subsequent OS update.
