Jim Klein, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com /daily-live/current/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux <replace-with-bug-number> If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.13-rc5 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Changed in: linux (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/944929 Title: psb_gfx boot hang on Atom N2600 (GMA3600 Cedarview) Status in “linux” package in Ubuntu: Incomplete Bug description: psb_gfx causes kernel stall at bootup immediately after framebuffer initializes. Screen goes black and system unresponsive. Usual suspects - disable vt switching, console=tty1, nosplash, no plymouth, disable plymouth, hard set framebuffer mode - don't solve the problem. Problem also exists in mainline and vanilla upstream kernels with gma500_gfx, although gma500_gfx on 3.3rc5 gets slightly further in that it redraws the screen text after the framebuffer initializes at a rate of about 1 line every 3 seconds. If you wait long enough, kernel kicks out stalls as follows (on 3.3rc5): ioremap error for 0x3f675000-0x3f678000, requested 0x10, got 0x0 gma500 0000:00:02.0: GTT PCI BAR not initialized. gma500 0000:00:02.0: GATT PCI BAR not initialized.
