Upon doing an strace to figure out what might be going on, I see this: <...much activity...> 28261 write(3, "0032want 8ba130df4b67fa40878ccf80d54615132d24bc68\n", 50) = 50 28261 write(3, "0032want 7df8ea909888d4856d3aff1c41192739d715a393\n", 50) = 50 28261 write(3, "0000", 4) = 4 28261 write(3, "0009done\n", 9) = 9 28261 read(3, "0008", 4) = 4 28261 read(3, "NAK\n", 4) = 4 28261 gettimeofday({1154968213, 166810}, NULL) = 0 28261 open("/home/bos/git/ofed_1_1/.git/objects/pack/tmp-ZbzARk", O_RDWR|O_CREAT |O_EXCL, 0600) = 4 28261 gettimeofday({1154968213, 167511}, NULL) = 0 28261 read(3, ... <...HANG> >From which I conclude that the server is telling the client to go away, which the client is for some reason ignoring.

In the mean time, you could clone using http and later on switch to git transport.

It seems like Mellanox doesn't publish that repository over HTTP, so I'm stuck. Tziporet, can you upgrade your git installation, please?

Tziporet, can you upgrade your git installation, please? In the meantime, you can try to specify a local clone of the mainline Linux repository with the --reference=... option to git-clone. Then the server will need to send only objects which do not exist in the mainline tree, and should be able to prepare the pack faster. ``` ## Bryan O'Sullivan, 2006-08-07 18:23 Subject: Re: Problem with clone hanging Message-ID: <1154975000.26375.86.camel@sardonyx> URL: https://gitlist.dev/e/1154975000.26375.86.camel%40sardonyx In-Reply-To: <20060807215201.b54da1ce.vsu@altlinux.ru> ``` On Mon, 2006-08-07 at 21:52 +0400, Sergey Vlasov wrote: > In the meantime, you can try to specify a local clone of the mainline > Linux repository with the --reference=... option to git-clone. Thanks. I don't know if what I'm cloning is actually a kernel tree, unfortunately.

Of course, it might contains some completely unrelated branches (with git this is possible), but at least you won't need to download the whole kernel history since 2.6.12-rc2. ``` ## Michael S.

It's a kernel-tree + other stuff. -- MST ``` ## Bryan O'Sullivan, 2006-08-07 22:26 Subject: Re: Problem with clone hanging Message-ID: <1154989613.26375.104.camel@sardonyx> URL: https://gitlist.dev/e/1154989613.26375.104.camel%40sardonyx In-Reply-To: <20060807183230.GA14955@procyon.home> ``` On Mon, 2006-08-07 at 22:32 +0400, Sergey Vlasov wrote: > On Mon, Aug 07, 2006 at 11:23:20AM -0700, Bryan O'Sullivan wrote: > > On Mon, 2006-08-07 at 21:52 +0400, Sergey Vlasov wrote: > > > > > In the meantime, you can try to specify a local clone of the mainline > > > Linux repository with the --reference=... option to git-clone. > > > > Thanks.
