I did a bisect between the following 2 commits: 61c4f2c81c61f73549928dfd9f3e8f26aa36a8cf (good) Linux 2.6.39 and 55922c9d1b84b89cb946c777fddccb3247e7df2c (bad) Linux 3.0-rc1 Both commist were tested by me on my machine. And Linux 3.0-rc1 hangs on my machine but Linux 2.6.39 works fine. And the bisect couldn't find the commit which causes hangs on my machine. All commits which were provided by the bisect were bad. And the commit before tha last bad bisect commit was bad too. I did bisect several times, and got the same results. Fo testing i used linux-3.0.y branch of git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git. Did i miss something or do something wrong here ? Regards
