Screensavers crash on AMD 1049

[kramer2k]

So I just noticed that certain screensavers are crashing system prefs when i try to select them in 10.4.9. They all work fine on 10.4.8

Flurry, computer name, RSS, iTunes artwork, and spectrum work GREAT...

The others that require slides DON'T --> Beach, cosmos, nature, paper shadows, forest...
When I try and select them, system prefs crashes...attached is the log...

AMD Venice 3400+ running 10.4.9

same problem with changing screensavers here
(i attached the crash log)

cpu: AMD athlon64 3200+ (939) - sse3
mobo: ASUS a8v (via k8t800 pro, vt8237)
gpu: NVIDIA 7600gt agp 256mb (gainward golden sample)

installed using tubgirl's OSX_1048_AMD.iso and upgraded to tubgirl's 10.4.9_test using netkas's instructions from his blog (also downloaded amd 8.9.1 kernel and some other files from irc.osx86.hu - room #1049)
using agpgart v2.1, natit v0.02 dual, and nvidiaEFI v1.02

btw, can you open "Extensions" in "System profiler"?
it crashes on me as well

[kramer2k]

yeah, i can open extensions in system profiler without a problem...

but still clueless about the saver issue..

I just tried updating my nForce4 AMD maching to 10.4.9 with 8.9.1 kernel. Screensaver options are opening up just fine here, just a ton of other problems (USB2, About crash, few minor issues). Used Netkas update method.

[kramer2k]

Maybe it's an opengl framework or soemthin that's not cpuid patched?

Can ANYONE on AMD test this to see if they have screen savers?

I can confirm this is happening with a P4 sse2 processor too (8.9.1 kernel).
It doesnt happen if I replace the kernel with the 8.8.1

Same problem here. Selecting the Screen Savers tab in "Desktop & Screen Savers" in System Preferences crashes System Prefs on my Pentium M SSE2 machine when running the 8.9.1 kernel. The crash does not happen if I replace the kernel with the older 8.8.1.

[kramer2k]

Holy smokes! It is a 10.4.9 kernel issue!

Just went back to 10.4.8 kernel (ND-23) and now the savers work...

maybe the 1049 kernel not playing nice?

Hi all ,

I have the same problem with screensaver with the new kernel Intel SSE2 8.9.1
I replaced it with the 8.8.1 and all is ok now.

Just for your information

[tester312]

Division by zero in ASI_NumberOfCPUs, eh? Perhaps netkas should hack this into 10.4.9's cpuid_set_info function:
//Bug in Northwood HHT P4 and possibly some AMD multicore
if (cpuid_cpu_info.cpuid_cores_per_package == 0)
cpuid_cpu_info.cpuid_cores_per_package = 1;
In the meantime, could one of you post your "sysctl -a" output? Wouldn't be surprising if there's a suspicious zero value for a variable such as ncpu, cores_per_package, etc.

I have same problem here on AMD 1x...

[Apple][Guy]

Scrensavers work fine on my AMD 64 X2 with 10.4.9 kernel

Here ya go...

yeah, check it out...

Just letting peeps know that this issue has been fixed in the new kernel!
Thanks again semthex!

I may be wrong, but I think the problem was only fixed for SSE3 processors. SSE2 8.9.1 kernel still crashes System Preferences when selecting Screen Saver. Just waiting for the changes to trickle down to the SSE2 kernel!

EDIT: Tried the newest 8.9.1 SSE2 kernel, and it is now fixed!! Thanks.
