dierre, thank you for reporting this bug and helping make Ubuntu better. 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? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .
If it remains an issue, could you run the following command in the development release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report. apport-collect -p linux <replace-with-bug-number> Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results. Thanks in advance. ** Summary changed: - Kernel won't boot and complain about a bug on acer aspire 5630 + kernel BUG at /build/buildd/linux-2.6.38/mm/slub.c:2747!; RIP: 0010:[<ffffffff8115650b>] [<ffffffff8115650b>] kfree+0x11b/0x120 ** Tags added: kernel-oops needs-upstream-testing ** Summary changed: - kernel BUG at /build/buildd/linux-2.6.38/mm/slub.c:2747!; RIP: 0010:[<ffffffff8115650b>] [<ffffffff8115650b>] kfree+0x11b/0x120 + WARNING: at /build/buildd/linux-2.6.38/fs/sysfs/dir.c:455 sysfs_add_one+0xc8/0xf0() ** Description changed: Binary package hint: linux-image-2.6.38-8-generic - On my acer aspire 5630 the boot process will not complete unless I pass - acpi=off as boot kernel parameter (but then the wifi won't work). + On my acer aspire 5630 the boot process will not complete. + + WORKAROUND: acpi=off as boot kernel parameter (but then the wifi won't + work). + + WORKAROUND: installing the restricted drivers for the nvidia video card.
