Do you get the USB warning if you boot from the Install Disc?

Thanks for the interest BD. This morning I started my imac and again got five or six USB warnings in a row. But this time my periferials worked, and my bluetooth didn't, it was completely deactivated. I did a boot from the installation disk following your question, and from the installer's Disk Utility I performed a "Verify disk" check and got no errors. Also no USB warnings in there. Then I quit the installer an rebooted from my HD volume, and the first thing I got on the screen after the grey apple was the USB warning. But at this point was again only one, and my periferials are working and my bluetooth too.
Has all this erratic stuff any meaning to you? Is it safe that I just keep going on ignoring the warnings, or they have a reason? Or is the only reason that my imac went bananas after the upgrade?

Thanks Tom , I've already read the first article and tried everything on it, but the second one has a couple of things i didn't tried yet (I already went through the most obvious ones like clearing caches, checking connections, doing PRAMs, plug/unplug, etc) The USB prober test and the revert of kernel extensions sounds very misterious, but I'll give it a try. Also the firmware update looks like a good idea!

I think it's serious, but if it didn't do it booted from Install Disc then Software is highly suspect.
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
Did we get the warning in Safe Mode?
