Luca Zenatti, 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> Also, could you 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-rc3 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. ** Tags added: bios-outdate-v1.23 ** Changed in: linux (Ubuntu) Importance: Undecided => Medium ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete ** Summary changed: - [Kernel] ACPI: EC: input buffer is not empty, aborting transaction + [Acer Aspire 5930] ACPI: EC: input buffer is not empty, aborting transaction -- 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/578506 Title: [Acer Aspire 5930] ACPI: EC: input buffer is not empty, aborting transaction Status in “linux” package in Ubuntu: Incomplete Bug description: On my notebook acer aspire 5930G on upgrade to 10.04 version, after few minutes of use apci stops working (don't recognize ac/dc or battery, don't change lcd blacklight, etc.) and start to flood dmes with this messages: [ 767.208058] ACPI: EC: input buffer is not empty, aborting transaction [ 767.208072] ACPI Exception: AE_TIME, Returned by Handler for [EmbeddedControl] (20090903/evregion-424) [ 767.208106] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.LPCB.EC0_.GBST] (Node f7017030), AE_TIME [ 767.208197] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.LPCB.EC0_.BAT0._BST] (Node f7017120), AE_TIME [ 767.208277] ACPI Exception: AE_TIME, Evaluating _BST (20090903/battery-393) Trying to reboot (or to shutdown and restart) my pc don't want to boot!
