I experienced the same problems on another H55 motherboard : Gigabyte GA-H55-UD3H, with a Core i5 650 processor. It looks like the latest kernel of ubuntu 10.04 (2.6.32.12) correctly supports my motherboard and CPU.
I started on the ubuntu 10.04 alpha 2 liveCD (without any acpi startup command), and installed the system on the hard disk. The installed system was not stabled with the kernel version of the alpha 2 CD (2.6.32.10). I had to start in recovery mode, and install all the updates (apt-get update, apt-get dist-upgrade) Now my system is stable and everything works : USB, audio (at least analog stereo), and opengl video -- Cannot boot 9.10 with ACPI support on Intel DH55TC mb https://bugs.launchpad.net/bugs/507770 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
