Similar experience on my Dell E1505 (aka 6400) with ATI video card. Suspend works sometimes, but hibernate will not resume. This happened after I upgraded from hardy. So, I tried doing a fresh install, but have the same experience. I tried both 32-bit and 64-bit versions of intrepid, with the same result.
I edited the grub boot line to elimate "quiet splash" and noticed that the resume successfully unpacked the resume image file, but hung at the next step with the error message: suspending consoles (use no_console_suspend to debug) I tried this at the end of the boot line and it showed a little more messages, but still did not show any errors. It just hangs, -- suspend/resume broken on dell Latitude E6400 kernel 2.6.27-3 https://bugs.launchpad.net/bugs/269490 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
