Stuck at "DSMOS has arrived" after updating to 10.8.2

[lopezimg]

Hello again.

I've got a problem with Mountain Lion 10.8.2. I just installed an update from AppStore and when I try to boot it stops at "DSMOS has arrived".
Is there any way to fix this? I've got a XFX 6870 card.

Regards.

same here.
I am able to boot if I get if it a -f on the boot prompt, which ignores the kernel cache. but even after going in and deleting the startup cache it still crashes if I dont use that flag
