Public bug reported: I am preparing for deployment of Ubuntu 10.04 on servers. We deploy Ubuntu using the netboot image, on a PXE server. Two particular systems have been troublesome for us. Note that we are using the latest netboot image (dated from this morning).
Steps to reproduce: -Boot on netboot image -Install Ubuntu. (we are using a preseed file, attached). -After installation, the system reboots. -The BIOS hangs after detecting hard disks, right after: Ultra DMA Mode-5, S.M.A.R.T. Capable and Status OK Now, there is nothing we can do. I would normally not file a bug against Ubuntu for this, but I have never seen this before. Installing Ubuntu Karmic or even Hardy works perfectly. Using a disk installed on such a motherboard in a newer one (different model) works 100%. Using Lucid installed in a newer board on this motherboard model does the same thing. It looks like Ubuntu does something with the disk that 2 different motherboards dislike. The affected motherboards are: -Asus P5P800-MX (Intel 865GV chipset) -Asus P5GZ-MX (Intel 945GZ chipset) I have tried updating BIOS versions without success. These 2 boards have very similar BIOS interfaces (AMIBIOS). I have tried modifying SMART detection settings without success. The same installation works on these much newer motherboard: Supermicro C2SBM-Q Asus M4A785-M We have tested this on multiple affected motherboards (all same model), with the same results all the time. I think this is pretty important for the final release, as this would be a problem to many people with older hardware. ** Affects: ubuntu Importance: Undecided Status: New -- BIOS hang - Unable to boot after installation https://bugs.launchpad.net/bugs/551965 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
