Vivek, I haven't found a good why to bisect this patchset. any ideas of how to break up the patchset to narrow this down or have you started to debug this yet? -Steve *** Bug 728424 has been marked as a duplicate of this bug. *** Created attachment 517798 [details]

Hmm..., So with the above patch series, system still works just that it takes a long time to boot. I am wondering if it is related to issue where queue deletion will get slow in case of CFQ. I had posted a patch for that upstream. I think a quick way to verify that will be using any other scheduler then cfq. How about using elevator=deadline on command line and see if you still see the issue. Can you please try following CFQ patch I posted upstream and see if issue is resolved. https://lkml.org/lkml/2011/8/1/259 (In reply to comment #8) > Can you please try following CFQ patch I posted upstream and see if issue is > resolved. > > https://lkml.org/lkml/2011/8/1/259 I'll build this patch and see if it fixes the problem ok, before building the patch, can you please do quick test of using elevator=deadline on kernel command line. This will atleast confirm that problem is with CFQ. If that's not the case then above patch will most likely not help.

Did you do a brew build across all arches or just a local build for ppc64? If you did brew build across all arches, i could skip that step. Otherwise i will do a brew build, and post the patch to rhkernel-list.
