Description Igor M Podlesny 2009-01-02 11:57:43 EST
Description of problem: Kernel hangs suddenly.

Keywords:	tcp_lp_rtt_sample
		divide error: 0000

Additional info:

Usually I don't use RedHat's kernel directly, but OpenVZ's based on RHEL's. Please refer to mine bugreport to OpenVZ:

The upstream commit URL:

I'm now building the testing kernel packages to test.
Comment 2 Ivan Vecera 2009-01-13 11:45:54 EST
Promised kernel packages are available at:

Could you please test them and report back results?
Comment 3 Igor M Podlesny 2009-01-13 18:12:00 EST
> Could you please test them and report back results?

My bugreport to OpenVZ project contained patch, I had backported from mainstream by myself:


Since the moment I had sent the patch to OpenVZ, I was using the patch (even a bit earlier, actually). The patch is trivial and it doesn't really require any complex testing, actually I was tested since 2.6.26 came out. OpenVZ's kernel I was using started at last working w/o hangs since I had applied it.

So, put the patch into new RedHat kernel's releases ASAP, don't waste time -- it's a nasty bug and your customers shouldn't have it for such a long time since it was fixed in mainstream.

OK, I treat it as successfully tested.
