[Kernel-packages] [Bug 1037094] Re: writing `/dev/mem': Bad address Error writing to ACPI area with 32 bit kernel
Christopher, this is no longer giving me a problem as bug 806032 has been fixed. However I have checked with Trusty (kernel 3.12.0-7 32 bit) and the problem described here does still exist. The bug is therefore not invalid, but from my point of view it does not need fixing. I don't know what the convention is in such cases. Won't Fix might be more appropriate but it will not let me set it to that. -- 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/1037094 Title: writing `/dev/mem': Bad address Error writing to ACPI area with 32 bit kernel Status in “linux” package in Ubuntu: Incomplete Bug description: Using the 32 bit kernel I am unable to write to the ACPI memory area using the command sudo dd if=value_file of=/dev/mem bs=1 seek=3660685688 count=4 This gives the error dd: writing `/dev/mem': Bad address 3660685688 is 0xDA31A178 and sudo cat /proc/iomem shows ... da216000-da32bfff : ACPI Non-volatile Storage ...

Colin Law, thank you for your comments. As outlined in https://wiki.ubuntu.com/Bugs/Status Won't Fix would be more appropriate, for example, if you desired the outcome noted in the Bug Description, and the maintainers didn't want to implement it on technical grounds. Given you are no longer interested in this being fixed, it's considered Invalid. However, if you change your mind in the future, this report could always be reopened, and resumed where it was left off. Thank you for reporting this and helping make Ubuntu better. Please feel free to report any future bugs you may find. ** Changed in: linux (Ubuntu) Status: Incomplete = Invalid -- 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/1037094 Title: writing `/dev/mem': Bad address Error writing to ACPI area with 32 bit kernel Status in “linux” package in Ubuntu: Invalid Bug description: Using the 32 bit kernel I am unable to write to the ACPI memory area using the command sudo dd if=value_file of=/dev/mem bs=1 seek=3660685688 count=4 This gives the error dd: writing `/dev/mem': Bad address 3660685688 is 0xDA31A178 and sudo cat /proc/iomem shows ... da216000-da32bfff : ACPI Non-volatile Storage ...
