*********** MASS BUG UPDATE **************

We apologize for the inconvenience.  There is a large number of bugs to go through and several of them have gone stale.  Due to this, we are doing a mass bug update across all of the Fedora 20 kernel bugs.

Fedora 20 has now been rebased to 3.17.2-200.fc20.  Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.

If you have moved on to Fedora 21, and are still experiencing this issue, please change the version to Fedora 21.

If you experience different issues, please open a new bug report for those.

Comment 4 Andrew Vagin 2014-12-26 13:29:42 UTC

Any news? CONFIG_CHECKPOINT_RESTORE is set for x86_64. It doesn't enable arch-specific code, so it should be safe to set this option for arm too.

Comment 5 Peter Robinson 2014-12-26 14:09:03 UTC

Any reason not to set it for all architectures (PPC/s390) too?

Comment 6 Andrew Vagin 2014-12-26 14:18:05 UTC

I don't see such reasons.

JFYI: I am not sure that anyone except CRIU uses checkpoint/restore functionality in kernel. CRIU suports x86_64, ARM, ARM64.

Comment 7 Peter Robinson 2015-01-15 03:27:07 UTC

kernel now built with support in F-22 (kernel-3.19.0-0.rc4.git2.1.fc22)
