http://bugzilla.kernel.org/show_bug.cgi?id=15341 --- Comment #15 from Jens Axboe <axboe@xxxxxxxxx> 2010-02-25 13:34:23 --- OK, that's good at least. We need to do something about 2.6.32, though. If you are willing to try and bisect the problem, it would be much appreciated. Checking revisions between 2.6.31 and 2.6.32 for CFQ, there are only 12 of them. So you would not need to compile and check more than 4 kernels. The way you would do this, is git clone Linus -git tree: $ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git $ git checkout v2.6.32 Start the bisect testing: $ git bisect start block/cfq-iosched.c $ git bisect good v2.6.31 $ git bisect bad v2.6.32 Now copy in your .config and run make oldconfig and compile the kernel+modules like you always do. Boot and test the kernel. Lets assume this first test is good, you'd then cd back into your source directory and do: $ git bisect good which would hand you a new revision to build, boot, and test. Likewise, if the resulting kernel image didn't work well, you would run $ git bisect bad instead. You repeat this until git tells you what the bad revision was. And then you post that here :-) -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. -- 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
