Please give it a try anyway. If you look at the mail threads on lkml that are referenced from the BR you'll see that this bug resulted in different hangs at different points with both 2.6.27 and 2.6.29 [1] in the Hercules emulator. Bisection pointed to different, completely unrelated changes that somehow triggered the bug even though those changes in themselves were completely correct. The hangs on Hercules were rather unpredictable as 2.6.26, which also has the bug, worked reliably. I don't think it really matters if it's emulator or real hardware. The determining factor is what type of system it is. The bug itself is a rounding error in fairly core s390-specific (31 bit) code, so the fact that s390x does not hang actually increases the chance that this is related. Where exactly the bug manifests itself varies, but when it does it's been completely reproducible and the result in each case was an endless loop: a hang. I'm not saying this definitely is the cause, but it looks similar enough to me that it's worth giving the patch a try. I agree that the remaining Flex-ES issue is completely unrelated. [1] With 2.6.29 I could get as far as the login prompt, but actually logging in would trigger the hang. -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of "unsubscribe".
