Startup freeze after migrating to new i7 iMac
Authored by: Marcel Bresink on Apr 09, '11 12:29:57AM
As the author of the BRESINKx86Monitoring kernel extension, I'd like to add some notes here: It is a general problem to migrate or clone old hardware drivers to new hardware models.

The Kernel Panic mentioned in this thread can only occur when a version of the BRESINKx86Monitoring driver from January 2009 or even older (this was 7 product releases ago!) is being copied to a system with Intel Core i technology. Certain specifics of Core i processors were not known in early 2009 yet, so the drivers of that time could not foresee a certain incompatibility which can lead to a Kernel Panic. This issue was immediately fixed when Apple released the first Core i systems in March 2009.

The general hint to give here is to check the system installation for hardware-specific software, and to update these software products to their latest releases before cloning. This will avoid such problems before they can occur, and the migration will run smoothly.

Just so you know, I wasn't pointing fingers at your work Marcel, I suspected the case was exactly as you described. Something new came along that could not have been anticipated. Thank you for confirming my suspicions! I appreciate your work on the temp utility.

From now on I will check the start up items before any more migrations. Most likely in 4 years since this spiffy new iMac seems pretty solid.

One funny co-incidence, I moved the old tower into another room and the display stopped working. The power indicator blinks 3 times, so it's off to Apple for service. I suspect my old system is jealous of the iMac.

I have enjoyed this site for some time, so I am hoping in a small way I'm giving back by sharing my experiences.
