Right, if the driver consistently fails in 2.6.39 and runs fine in 2.6.37 then you can use git bisect [1] to possibly find the commit that broke things. git bisect start git bisect bad v2.6.39 git bisect good v2.6.37 <run test> git bisect good/bad depending on test results. Although you might try 2.6.38 first to cut down on the number of kernels you need to test. -- Dan [1]: http://www.kernel.org/pub/software/scm/git/docs/git-bisect-lk2009.html -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
