I have a reproducible problem with git-index-pack getting stuck. 
Is this a known problem fixed in one of the later releases? 

git --version
git version 1.4.4.2

git-clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
linux-2.6-wk
remote: Generating pack...
remote: Done counting 445435 objects.
remote: Deltifying 445435 objects.
remote:  100% (445435/445435) done
Indexing 445435 objects.
   0% (194/445435) done

It stays there for ever. If I attach to all the git-* processes using strace
here is what it shows -

 strace -p 9055  # This is git-index-pack
Process 9055 attached - interrupt to quit
read(0, 0x8063ba0, 4096)                = ? ERESTARTSYS (To be restarted)

Are you on Mac OS X?  We found that earlier versions of index-pack on
that platform ran poorly unless we used pread().  A change was made
in 1.5.0 to switch to pread for all platforms, which significantly
improved performance.

I'd upgrade your Git, the current version is 1.5.1.1.

Nope, I am on Linux. But I did some more debugging and found that my
router is the culprit - it has ACK errors in the logs and things start
working fine if I switch to another router.

Yes, on my list.

Thanks
