Hello!

I decided to try osx86 after a couple of years and immediately ran into problems. I've tried so far installing ideneb 1.5 and xxx 1.0.5.6 but both give me the exact same problem (as both have Voodoo 9.5.0). I cannot even start the installation as the error pops up quite early. I've tried cpus=1 so far but cannot think of anything else.

Code:

panic(cpu 0 caller 0x001AC05E): "Voodoo rtclock_init panic"@VoodooKernel/xnu-1228.7.58/osfmk/i386/commpage/commpage.c:425

Specs:

CPU: Phenom II 550BE (unlocked 4 cores)
Memory: 4 x 800 MHz DDR2
Video: Radeon HD3850
Mainboard: Asrock A790GMH/128M 790GX + SB750 Chipsets

Any ideas anyone?

Update: Got it working with Vmware, might try installing that to HDD...

Same problem here.

motherboard: TA790GX128, ver 5.2
Memory: 4GB, DDR2 1066
CPU: Phenom II 920 X 4 (quad core) 2.8Ghz

I can't get the initial screen, or I can get to the "Apple" screen, but then the system just locks up. I've tried changing my SATA to ACH (I think), but that didn't work either. If I can just get past the initial screens, I may have a chance.

I had the same problem on my IBM ThinkPad X40. The only result google found was this page, and there was no solution here.
I started looking for commpage.c's source over the net, and even found it, but line 425 contained no code, but comments, so this wasn't really help.
Searching for rtclock_init() function over google showed me that this function is related to the rtclock set of functions, which are RealTime Clock functions.
In addition, this problem occurred only when I was trying to boot without the AC power. I opened the BIOS Manager utility and started looking on the options. I tried to match every option to be the same for AC power and battery, and I succeeded to boot without AC power. After playing a bit more with the settings I found out that the Intel SpeedStep technology option was interrupting, so I disabled it.

Later I was looking for threads of people who also installed OS X on their X40 and found a guy who described my problem and solution:
Mac OSX sur Thinkpad X40 - Le Portal Pacher (This is French. You can find the translated version via google translate: Google Translate)

I hope you will find this information helpful.

So Cool'n'Quiet might be the issue. I have to play with bios settings and see if some sort of combination works.

I had the same problem getting my Phenom II 550 to boot. Simple fix; add this boot flag (works for booting DVD install too) busratio=X where x obviously is what your cpu multiplier is (default for the 550 is 15.5).

Any progress with this? did you check Phenom II in the HCL?

I was getting same error while installing iDeneb 10.5.8 Lite edition.
Thanks Bansaku... busratio=18 worked like a charm for my AMD Phenom II X2 550 processor.

Busratio=16 worked for me, thanks a lot bansaku!

busratio=18 seems to be doing the trick in vmware. Excellent

Hi,
I got the same during instalation ideneb 1.6 (Darwin Kernel 9.5.0):
panic(cpu 0 caller 0x001AC05E): "vOODOO rtclock_init panic"@/VoodooKernel/xnu-1228.7.58/osfmk/i386/commpage/commpage.c:425
Could you explain me how to make boot flag on DVD ideneb?
