10.6.8 kernel panic at startup (fixed)
**excuse my english since I'm french**
Like a lot of people, I've installed 10.6.8 through software update. And I've experimented kernel panic at startup. So, I unplugged everything (my two USB hubs with multiple peripherals) except the original Apple keyboard and Apple wired mouse. And restarted in safe mode. Downloaded Apple 10.6.8 combo update, install it and restart. Everything went fine. Great.
But as soon as I plugged back my USB hub, kaboom! here's come the Kernel Panic again.
So, one by one, I plug and unplug my peripherals. To discover that my old optical wired two button mouse (love that mouse ;-))) was THE problem. Even when it's plugged directly in one of the USB port on my Mac Pro. I've try with three different optical USB wired mouse, one Logitech, one Dell and one Verbatim (my old mouse): kaboom! Kernel Panic. With my Microsoft optical wireless mouse? No kernel panic. 10.6.8 crashes only with third partys wired mouses, except the Mac wired mouse.
Voilà.
So, I'm stuck with the old wired Apple Mouse (that I hate). But no more kernel panic.
Hope my story can help someone.
And Apple, I missed my optical two buttons wired mouse. ;-))
