Description Alexis Lahouze 2016-02-18 11:37:39 UTC

A bug in fs/xfs/xfs_trans_ail.c prevents the kernel to suspend to memory.

Here is the commit fixing the issue, but it seems not to be integrated in 4.4.2:

https://git.kernel.org/cgit/linux/kernel/git/dgc/linux-xfs.git/commit/fs/xfs/xfs_trans_ail.c?h=for-next&id=18f1df4e00cea2eae41f3e5515b94d1e7127b2b6

Please add it in a patch in gentoo-kernel package.

Comment 1 Alexis Lahouze 2016-02-18 11:41:27 UTC

To reproduce it, you just need to have a kernel >= 4.4.1, a mounted xfs partition, and try to suspend to RAM, or hibernate.

Comment 2 Alexis Lahouze 2016-02-26 09:36:18 UTC

This patch is still not included in the recent 4.4.3 release.
