I guess you're talking about 44ecf1df9493e6684cd1bb34abb107a0ffe1078a, which ensures a 10ms msleep call. We don't have this patch, but as with CONFIG_HZ=100, msleep() calls are anyway rounded up to 10ms, so I'm not sure this patch will have a huge impact. But we will try. Then, there is also de99d5328c6d54694471da28711a05adec708c3b, but it doesn't seem to be related to our problem. But we will also try with that one. > If you cannot find it, let me know and I will dig around my archives > and find it for you (I'm actually at work right now so it would be > inopportune for me to do it right this minute). :-) Thanks for your very quick feedback!
