spock84 Posted February 7, 2008 Share Posted February 7, 2008 I'm experiencing random system lockups (everything freezes and I have to reboot) and I can't see anything about any of them in system.log (should I look elsewhere?). There doesn't seem to be any easily deductable pattern to them. This happens with both the mach and the vanilla kernel. I don't even get the dreaded "You need to reboot"-screen. Anyone know what this can be? Other than these lockups, everything works perfectly, so any help is much appreciated. Installer: Kalyway Hardware: Asus P5KC 4GB DDR2 PC6400 Core 2 Duo E8400 Old IDE hard drive (where Leopard is installed) SATA drive with Linux and an empty NTFS partition. XFX GeForce 8400GS CNet CWP-854 (Ralink RT2500) Logitech USB mouse and keyboard 0 to 4 external USB harddrives Drivers: NVinject (installed with most recent pack from johnniecarcinogen) Official Ralink driver Other, non-supported hardware present, not detected: Pinnacle TV card Soundblaster Audigy SE Link to comment https://www.insanelymac.com/forum/topic/86412-random-lockups/ Share on other sites More sharing options...
~pcwiz Posted February 7, 2008 Share Posted February 7, 2008 I had this problem too, it turned out to be a unstable kernel and high processor temperatures which is never a good combo. Keep tabs on your CPU's temperatures and if you are running Leopard, try downgrading to Tiger and see if you experience the same problems. If you don't have the same problems with Tiger then it means an unstable kernel.

physicallymac Posted February 8, 2008 Share Posted February 8, 2008 I have similar problem as spock84 and am running very similar hardware (except with quad core processor). I have monitored core temps and have not noticed any abnormalities. I have already been forced to reinstall Kalyway 10.5.1 after first system crash, which I was not able to restart from. Both installs went smooth and start up fine but crash during processor intensive activities. If I do have an unstable kernel how could I repair that and still maintain running osx86 and preferably leopard?

Grooby97 Posted February 8, 2008 Share Posted February 8, 2008 can you SSH into your mac after it locks? i have something similiar and when I SSH into the mac and ran "dmesg" as super user, it shows a lot of error messages regarding my graphic card. NVGraphic something something. I have installed the latest version of the 10.5.2 kext install script (found it somewhere online) and so far I've not encounter this random lockup..but i am still testing.

spock84 Posted February 8, 2008 Author Share Posted February 8, 2008 That's a good idea. Might just be the GUI that freezes. Will try that later, and maybe the two computer debugging method I read here somewhere. Or just to make it simple if that doesn't work; try running it without NVinject and see if the error persists.

spock84 Posted February 9, 2008 Author Share Posted February 9, 2008 I kind of solved this now, I think. Been up for more than half an hour, converting videos with VisualHub (which is what I did the other times), whilst earlier it took 6-7 minutes before it crashed. The solution was to set maxmem to 2048 instead of the 4 gigs I actually have. I don't get why this happens though. I thought OSX was 64bit?

Viscaria Posted February 10, 2008 Share Posted February 10, 2008 Try enabling AHCI in BIOS. Link to comment https://www.insanelymac.com/forum/topic/86412-random-lockups/#findComment-615943 Share on other sites More sharing options...
chainsaw1972 Posted April 21, 2008 Share Posted April 21, 2008 Spock, I was having this same problem. Some cpu-intensive macos apps would cause my system to lock up. But I don't think its CPU temps or AHCI support... I think the nvinject easy installer was installing a custom kernel from a macbook pro which uses the GeForce 8600GT chip. If you look at the specs for the MacBook Pro with the dual core proc, it can only handle 2GB ram max. Perhaps theres a connection. Setting maxmem=2048 resolved the lockups for me. Sucks since I have 4GB. Link to comment https://www.insanelymac.com/forum/topic/86412-random-lockups/#findComment-718222 Share on other sites More sharing options...
