stemann Posted January 11, 2010 Share Posted January 11, 2010 Hi, I've been experiencing a weird problem on Mac OS X v10.6.2 using the 64-bit kernel on a P55 motherboard (Gigabyte GA-P55-UD4). I get a kernel panic once a USB flash drive is attached after the machine has slept -- or equivalently, a kernel panic when the machine wakes up after having slept with a USB flash drive attached. A workaround is using the 32-bit kernel by including the kernel flag arch=i386 in /Extra/com.apple.Boot.plist. There are no problems with the 32-bit kernel. The machine: Gigabyte GA-P55-UD4 Intel Core i7-860 + stock cooler Kingston ValueRAM DDR3 1333 MHz DIMM RAM Gigabyte GeForce 9600 GT (GV-N96TSL-1GI) WD Caviar Green 1.5 TB Samsung SATA DVD-RW is running: Chameleon 2.0-RC4-r684, with Rekursor's patched boot v2. Custom extracted, fixed, and editted DSDT with patches (including sleep) provided by tonymacx86. Vanilla Mac OS 10.6.2, except for: Ethernet through RealtekR1000SL.kext. Sound through 10.6.0 AppleHDA.kext, LegacyHDA.kext for ALC888, and HDEF DSDT patches. Any ideas to what is the cause for this 64-bit kernel panic?

WinstonAce Posted January 11, 2010 Share Posted January 11, 2010 The problem is in your DSDT I have similiar thread somwhere here in the forum I also used dsdt from tonymac site. I patched my own DSDT and now everything is working, including sleep. tony done a great job on the dsdt's but changed some addresses which he shouldn't you could use my dsdt for reference ud4p.dsl.zip Link to comment https://www.insanelymac.com/forum/topic/206818-kernel-panic-when-usb-flash-drive-attached-after-waking-from-sleep/#findComment-1382548 Share on other sites More sharing options...

I patched my own DSDT and now everything is working, including sleep. tony done a great job on the dsdt's but changed some addresses which he shouldn't you could use my dsdt for reference I tried looking at the DSDT you posted in this thread and the copies you posted in the other thread, but looking at a diff of the DSDTs did not help me much -- too many lines changed to yield a clear picture. Could you elaborate on which addresses Tony changed that he should not have changed?
