Hi all. I've read all the other SATA threads for 10.5.2 here and on insanelymac and haven't been able to see if the problem has been solved yet. Just an FYI i've had completely working installations of tiger 10.4.8 and zeph's 10.5.1 release on the same hardware/HD. the DVD starts and installs fine. i installed to a Hitachi Deskstar 160 Gb SATA drive. i customized the install with NVInject 320 MB, and ToH 9.2.0 kernel, and EFI v8 MBR. install went fine. my primary OS is ubuntu so i added an entry to my grub bootlist by adding boot_v8 to /boot in linux. that's all fine, once selected from the grub list i pick the right HD and leopard starts the boot process until "still waiting for root device" begins, no panics before that (or else i imagine the boot wouldn't get that far anyways). anyways, i'm just wondering what the difference may be since 10.5.1 worked OTB (with the exception of geforce panics) and why 10.5.2 won't.

AMD Athlon64 X2 4200+
MSI Neo-4F (nForce4 chipset/lan)
2 GB corsair ram
1x WD 160 GB IDE HD (Vista)
2x Hitachi 160 GB SATA HD (Ubuntu on one, OSX on the other)
1x WD 500GB USB HD
evga geforce 8800 gts 320MB
1xLG (something) 16x dvd-r/rw
1x pioneer 111d 16x dvd-r/rw

think that should be all relevant specs.
oh and both the working 10.5.1 install and the 10.5.2 were done after formatting the SATA HD.

thanks for any help and thanks to zeph for all the great work!
