Known issues: 1.KASLR causes intermittent hibernation failures. VM fails to resumes and has to be restarted. I will investigate this issue separately and shouldn't be a blocker for this patch series.
Is there any change in status for this? This has been noted since January. -boris
2. During hibernation, I observed sometimes that freezing of tasks fails due to busy XFS workqueuei[xfs-cil/xfs-sync]. This is also intermittent may be 1 out of 200 runs and hibernation is aborted in this case. Re-trying hibernation may work. Also, this is a known issue with hibernation and some filesystems like XFS has been discussed by the community for years with not an effectve resolution at this point.
