d-track Posted July 24, 2011 Share Posted July 24, 2011 i've been using SL for a year on the same configuration but i have the same issues through the upgrades (10.6.2-10.6.7). small issues however i would like to get rid of them. sometimes when i boot up my pc, the usb soundcard (Novation Nio) doesn't produce any sound, but it is powered (the led lights) while other usb devices such as my keyboard and mouse is working fine. then i have to reboot the computer and everything is okay. this happens about once per 100 boot. audio applications can't detect this, they shows as everything is ok. the other issue is also very rare. completely freezes the machine, turns off soundcard etc but i always get the same screen: blinking symmetric same-sized colorful rectangles. only hard-reset helps in those cases. this issue is somehow related to graphics because most of the time i get this when working with adobe premiere or when i fullscreen a youtube video. this problem is hard to pinpoint because occurs once per month or even less. any idea? i already tried to play with bios settings and kexts but when i thought the problem's gone then occured again 2 months later two times a day... specs: Asus p5gcmx 1333 / C2D 2.66 / 2 GB ram / Intel GMA950 with the proper DSDT and kexts: fakesmc2.5 openhaltrestart nullcpupowermanagement uuplatformid Link to comment https://www.insanelymac.com/forum/topic/263424-random-usb-and-freeze-graphics-related-issues/ Share on other sites More sharing options...

d-track Posted August 3, 2011 Author Share Posted August 3, 2011 I have a very similar problem with the lockups, can you tell us how you solved it? well...at least it seems like its solved. usb soundcard problem is still around but turned out its not my hackintosh but the osx driver itself since a friend of mine uses the same device on a MBP and gets the same hang rarely but he told me doesnt need to reboot just replug the device. i did not tested this method because its not happened since but should be working. the freeze is not related to the soundcard problem. probably its my integrated gma950. there are guides floating here on the forums recommending disable peg root control. this is the only option in bios i haven't tried yet and no freezes since i disabled it. if it won't happen in the next weeks then that was it.
