ok, just got me a brand new 2010 MacPro 2 x 2.4 Quad-Core with 12GB Ram and the ATI 5870. This is the first MacPro to system boot into the 64bit Kernel by default (ie, hold 3+2 on restart to boot into 32bit Kernel).

One of the first things I did was run the Photoshop performance test, which FYI on my old G5 2.7 with 4GB Ram returned a time of 114 secs, and on the new Quad-Core in 64bit kernel returned a time of 14 secs, so as you can imagine I was pretty happy with the results.

Then the problems started...... when I was installing software I got the dreaded Kernel Panic, restart your machine screen. So I did, and it happened again on restart, so I did, and it happened again on restart, so I did.... you get the idea. So I put the system disk in and restarted, then reloaded OSX10.6.4 and everything seemed to be going fine, until I installed software again (different app from the first time), and I got the Kernel panic screen, then again on restart etc, so I booted into 32bit kernel and all is good.

EXCEPT!! - When running the Photoshop test in 32bit Kernel it returned a time of 17secs. Now, I know I am being picky here, but I do a lot of work in PSCS5, and by a lot I mean sometimes all day on large photographic images, so 3 secs is a big deal....

anyone know what is going on and how I can get back into 64bit kernel without panics.....😕😕
 
Oh this is not what I wanted to hear...🙁

That being said is OpenGL turned on in Photoshop? That may be the culprit. It causes endless problems for a lot of people. (Actually, I've never heard of anyone who said it HASN'T caused problems...)

OpenGL on my Apple 4870 here without any issues that i've found!!
 
interesting.... actually I've not ever had an issue with OpenGL using PS...

Anyway, I wasn't even using PS when the panic happened, just installing software, PS wasn't even open.... The machine is working fine in 32bit, had to use Terminal to permanently change the boot, but I would prefer to be using 64bit as that is kinda why I buy the high end mac in the first place (plus those valuable 3 secs🙂
 
Zeiss, please report back after your restore if everything is working. Glad I don't need Parallels anymore . . .

stupid Parallels was the problem - all is good now in full 64bit kernel mode, has been for about 12 hours....
