komodo-tux Posted January 14, 2009 Share Posted January 14, 2009 OK, I had a 10.5.5 retail Leopard installation using the Boot-132 method followed up with the Munky-EFI-bootloader. Everything was working (audio, video, all the PCI and USB) except for deep sleep. After upgrading to 10.5.6, I seemed to lose the function of whatever card was in the bottom PCI slot (wireless or ethernet; whichever was in that slot didn't work, but they were fine in other slots, so I don't think those kexts were a problem), also one of the usb hubs wouldn't work, and sometimes (rarely) shutdown wasn't complete. I went back to trying different Boot-132 discs to see if the kexts were the source of the problem. I had one with which all the problems mentioned went away, but video and audio were incomplete, so I thought it would be an easy job to get the right combination. No luck...all the logical combinations had one or more of the hardware problems (gave my burner quite a workout, tough). On a whim, I reinstalled the boot loader, and to my surprise everything worked (but sleep) with the kexts that I had been using all along. I was happy to accept this as a gift and not question why, but after 3 days, the problem is back, even though I've done nothing to the installation. I'm not expecting a miracle answer, but i would really appreciate some troubleshooting advice: is this a kext issue (such as power management kexts), should I fiddle with BIOS, could some plists have gotten modified that made the problems come back? The randomness of this problems is driving me batty and any help would be welcome. (BTW, I did try the update via software update, the combo updater, and the delta updater, and got the same problem each time). Thanks.

Pink Waters Posted January 14, 2009 Share Posted January 14, 2009 I experienced that same dilemma ! sleep went away with no reason, see my post Link to comment https://www.insanelymac.com/forum/topic/146775-here-today-gone-tomorrow/#findComment-1040338 Share on other sites More sharing options...
komodo-tux Posted January 16, 2009 Author Share Posted January 16, 2009 To update...in both installations the kext for the missing item (in this case the Broadcom wireless 4318) shows up under kexstat, but if I look at ioreg, in 10.5.5 the Brcm43xx driver is shown as a "child" of the 4318@ "nub", but in the 10.5.6 installation, it does not (see pictures below). Again I don't thinks its the kext per see, because it was working under 10.5.6 for awhile, or with different Boot-132 discs. But now, the driver is not being matched and loaded. Any ideas? Also, when I boot with -v I see something about the P states needed to be set, after mentioning the Intel SpeedStep kext (the hacked one in /Extras on the EFI partition). BTW why does the OSX dmesg show so little? I'm used to linux where you can see much more of the boot messages.

komodo-tux Posted January 24, 2009 Author Share Posted January 24, 2009 Update... everything is working again, but I'm not sure why. I did a software update, and it downloaded and installed updates for Safari, Quicktime, iphoto, iweb, nothing in the line of OS or security updates. After I rebooted, everything was working, and in ioreg the drivers are connected to the PCI nubs just like they are supposed to be. Not that I'm complaining, but the randomness of all this bugs be. Anyone have any ideas what goes on in a non-OS update that might have tweaked my system to work?

komodo-tux Posted January 24, 2009 Author Share Posted January 24, 2009 Well, as I feared, after another restart, the same problem was back... I think I'd get better odds in Vegas.

komodo-tux Posted February 14, 2009 Author Share Posted February 14, 2009 Just in case anyone had a similar problem... I was able to fix the problem permanently, but it took a little cash. I bought a $20 Rosewill RC-401-EX PCI-e X1 gigabit ethernet card with a Marvell Yukon 88E8053 chip from Newegg. It fit in the little 1X slot (first one on the bus), which allowed me to take out the old, slower 3com NIC, and move up the dysfunctional wireless card to a different PCI slot. Now everything works fine, all the time. Why having something in the last PCI slot on this motherboard would be a problem in 10.5.6, and not 10.5.5 will probably always remain one of life's little mysteries. BTW, the Rosewill card works really well in OSX, is was instantly recognized and configured. I also have Arch Linux on this box, and it only took an easy driver download to get working there. The Windows 7 beta... now that was a different story. I eventually got it to work once I manually told it to use a driver that it already had, but was insisting to me that it did not have. Anyway, I strongly recommend this ethernet card, as it fits in one of those slots that most things can't use, it was relatively cheap, and auto-configured.
