Hello, I had the same/similar problems with the Samsung R510, model: NP-R510-FS0ANL. (The last 2 letters of the model only identify the country you bought it in, like DE/NL/etc. so it is actually a NP-R510-FS0A)
I tried all the option under F6, (ACPI = off, etc), I tried different versions like Ubuntu 11.10/12.04 CD and DVD versions, both amd64 and i386... but every time the laptop would reboot right after selecting "Install Ubuntu", or trying to boot the live CD of Ubuntu. Now... I found the fix! Simply download the BIOS Update from the samsung website and install it via a windows live CD, after that the Installation works with no more unexpected reboots :) Hope this helps, enjoy!! p.s. you can change the brightness control for the monitor in the BIOS from automatic to manual, in case you have issues with it ;) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/354824 Title: Maverick 64-bit doesn't boot on Samsung R510 with 4GB RAM To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/354824/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
