I am chiming in as well. I have a Lenovo B510 All-in-one, i5 processors, 6GB RAM, 1 TB hard drive, ATI Radeon 5570, and tried to dual boot 11.04 64 bit. It wouldn't boot from CD/DVD, but booted through BIOS, and I didn't get any further than the language/Try/Install when I got the lagging black screen. I tried the acpi=on on and a few other options and still the same issue. I ended up installing 10.04...now my Wacom won't work (ha!), but I am hoping an upgrade won't give me the same results as a fresh install.
Consequently, it installed with no problems on my old computer (inVidia graphics card, with a bad hard drive), but the fan stayed on and abruptly shut down...again, bad hard drive, overheating problem, and not the Ubuntu install. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/759103 Title: [STAGING] (Regression) Kernel panic with 2.6.38-8 and acpi on To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/759103/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
