I have been trying to test these patches since yesterday afternoon.  When my machine is idle, they behave fine.  I started looking at performance to make sure they were a big regression by testing kernel builds with the scanner disabled, and then enabled (set to 120 seconds).  The scanner disabled builds work fine, but with the scanner enabled the second time I build my kernel hangs my machine every time.  Unfortunately, I do not have any more information than that for you at the moment.  My next step is to try the same tests in qemu to
see if I can get more state information when the kernel hangs.

Could you please send me your .config file ? Also, did you apply the
patches on top of straight v3.0 and what is your machine like ?

Thanks,


My .config will come separately to you. I applied the patches to Linus' master branch as of yesterday. My machine is a single Xeon 5690 with 12G of ram (do you need more details than that?)

Thanks,
Eric
