Does this error still occur with more recent kernel versions? If you're running Etch, could you try to reproduce this bug with the 2.6.24 based kernel added in 4.0r4? http://packages.qa.debian.org/l/linux-2.6.24.html Cheers, Moritz -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".

Bug#422111: download corruption
Package: linux-image-2.6.18-4-amd64 Version: 2.6.18.dfsg.1-12etch1 Hi, i have a very unusual, but reproducable bug: Downloading http://security.debian.org/pool/updates/main/l/linux-2.6/linux-image-2.6.18-4-amd64_2.6.18.dfsg.1-12etch1_amd64.deb should have md5 of 54b74bc3ba1204317c68bdf7a0d017e1, but my downloads gets corrupted. It happens only if the (slow 50kb/s instead of 5Mb/s) 128.101.240.212 mirror is used - the other mirrors are fine(!): $ wget --header "Host: security.debian.org" http://128.101.240.212/pool/updates/main/l/linux-2.6/linux-image-2.6.18-4-amd64_2.6.18.dfsg.1-12etch1_amd64.deb $ md5sum linux-image-2.6.18-4-amd64_2.6.18.dfsg.1-12etch1_amd64.deb eef84cc95c7c63fb6b90a90e839f3ccb linux-image-2.6.18-4-amd64_2.6.18.dfsg.1-12etch1_amd64.deb My other (non amd64) machines have no problem with this slow mirror, but the hw is not comparable. It is also fine, if i dont write to the disk, but handle the complete download in memory: $ wget --header "Host: security.debian.org" -O - http://128.101.240.212/pool/updates/main/l/linux-2.6/linux-image-2.6.18-4-amd64_2.6.18.dfsg.1-12etch1_amd64.deb | md5sum 54b74bc3ba1204317c68bdf7a0d017e1 - Pure disk read/write seems to be fine, too: $ dd if=/dev/urandom of=./r1.rnd count=4 bs=1024 $ cp r1.rnd r2.rnd $ cp r1.rnd r3.rnd $ cp r1.rnd r4.rnd $ md5sum *.rnd bfa67c39b57bde568af93803d302b3d9 r1.rnd bfa67c39b57bde568af93803d302b3d9 r2.rnd bfa67c39b57bde568af93803d302b3d9 r3.rnd bfa67c39b57bde568af93803d302b3d9 r4.rnd This problem appears on two identical (hw+sw) machines (Thomas Krenn Servers). Any ideas/hints ? Anything i should test to help you ? Thanks in advance...
