Can't clone Linus tree

Can't clone Linus tree

 Hi,

 yesterdat I wanted to bisect my kernel problem, but failed at first step:
cloning Linus' tree. Today I tried it on other system and also failed.

 This is git-1.4.0 on Slackware, i586:

%  git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git linux-git
fatal: packfile '/home/zdzichu/linux-git/.git/objects/pack/tmp-1jI4AH' SHA1 mismatch
error: git-fetch-pack: unable to read from git-index-pack
error: git-index-pack died with error code 128
fetch-pack from 'git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git' failed.

 And this is 1.4.0-1.fc5 on FC5, x86_64:
% git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git linux-git
fatal: packfile '/home/tomek/linux-git/.git/objects/pack/tmp-BxIcIC' SHA1 mismatch
error: git-fetch-pack: unable to read from git-index-pack
error: git-index-pack died with error code 128
fetch-pack from 'git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git' failed.

 Errors occur constantly since yesterday. They of course appear after
downloading several megabytes of data, which is unpleasant on my 128kbps
connection.

I am on ISDN here and i'm using rsync transfer since having problems
with other protocols too. Just replace the git:// with rsync:// in your
URI and try again.

Same here with both the master and next branch of git.  rsync as
suggested by Johannes Weiner works.  You can change the protocol
back to git in .git/remotes/origin after cloning; pulling small
changes seems to work fine.

strace tells me that safe_read at pkt-line.c:111 gets only 305 of
the expected 996 bytes and then dies.  I have no idea how that
might happen. :-/

Pulling the git repository works using the git protocol, btw.

Ah, I just saw this is a known problem and there's a patch by
Matthias Lederhofer, which Junio just accepted, I think (the
mail with subject "[PATCH] upload-pack: fix timeout in
create_pack_file)" on the git mailing list.

The problem is apparently that the server expects you (wrongly)
to finish your download session within ten minutes.  Until the
server is fixed you can use rsync:// for the initial clone and
git:// for smaller updates.

I saw that as well many times with both git vesrion 1.2.4 and 1.4.1:

git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git 
linux-2.6
Generating pack...
Done counting 293611 objects.
Deltifying 293611 objects.
 100% (293611/293611) done
fatal: unexpected EOF)      
fatal: packfile '/home/me/linux/linux-2.6/.git/objects/pack/tmp-FtdxDS' SHA1 
mismatch
error: git-fetch-pack: unable to read from git-index-pack
error: git-index-pack died with error code 128
fetch-pack from 
'git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git' 
failed.

Each time it fails after downloading approx. 60MB of data. Reported to vger 
git list with no response.
