Apologies for targeting the initial report to acpi-support. Further information:
This occurs on a fresh install using http://cdimage.ubuntu.com/xubuntu /daily-live/20070923/gutsy-desktop-i386.iso. I reinstalled to minimize upgrade errors. The kernel update afterwards produces the same oops (and is what was used in the dmesg). several of the /proc/acpi/ibm/ entries are missing which can cause monitoring applications to fail. $ ls /proc/acpi/ibm/ driver hotkey light video I tried patching the ubuntu source with thinkpad_acpi 0.16 (patches clean with offsets) but that still produces an oops. I then tried vanilla 2.6.22.9 from kernel.org and patch with 0.16 and there is no oops and the missing entries are back. $ ls /proc/acpi/ibm beep driver fan led thermal volume brightness ecdump hotkey light video In both cases .config was produced by copying /boot/config-2.6.22-12-generic and then 'make oldconfig' to try and eliminate configuration differences as a variable. I followed the procedure in https://wiki.ubuntu.com/KernelCustomBuild. ** Attachment added: "dmesg from 2.6.22.9 with thinkpad_acpi 0.16 (no oops)" http://launchpadlibrarian.net/9541643/dmesg-2.6.22.9 -- [gutsy] thinkpad_acpi oops on thinkpad t22 https://bugs.launchpad.net/bugs/145857 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
