reassign 685407 src:linux 3.2.20-1 fixed 685407 linux/3.5-1~experimental.1 tags 685407 + upstream patch moreinfo quit Hi again, Brian Kroth wrote:linux-image-3.5-trunk-amd64 (3.5-1~experimental.1) on the server does indeed appear to fix this.[...]Attached is a simple script I used to create a test dir for this. The ext4 volume was 3G.Very nice to hear. Please test the attached patches together against a 3.2.y kernel, for example using the following instructions. 0. prerequisites: apt-get install git build-essential 1. get the kernel history, if you don't already have it: git clone \ git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git 2. fetch point releases: cd linux git remote add stable \ git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git git fetch stable 3. configure, build, test: git checkout stable/linux-3.2.y
3.2.28
cp /boot/config-$(uname -r) .config; # current configuration scripts/config --disable DEBUG_INFO make localmodconfig; # optional: minimize configuration make deb-pkg; # optionally with -j<num> for parallel build dpkg -i ../<name of package>; # as root reboot ... test test test ... Hopefully it reproduces the bug. So:
It does reproduce the bug.
4. try the patches: cd linux git am -3sc $(ls -1 /path/to/patches/0*) make deb-pkg; # maybe with -j4 dpkg -i ../<name of package>; # as root reboot ... test test test ...
It does *not* reproduce the bug. Looks to have worked.
If it works, someone on the kernel team will probably apply the patches to wheezy (meaning they would automatically flow into squeeze-backports as well).
Good news. Let me know if you need anything else. Thanks for the help and good instructions, Brian
(An alternative set of instructions is at [1].) Hope that helps, Jonathan [1] http://kernel-handbook.alioth.debian.org/ch-common-tasks.html#s-common-official or the corresponding page in the debian-kernel-handbook package
