Hi folks,

We've had consistent suspend to RAM issues on today's upstream job, for
qemu-kvm.git

kvm.qemu-kvm-git.1.hp.raw.smp2.Fedora.11.64.linux_s3
kvm.qemu-kvm-git.1.smp2.Fedora.11.32.linux_s3
kvm.qemu-kvm-git.2.hp.smp2.Fedora.11.64.linux_s3
kvm.qemu-kvm-git.2.smp2.Fedora.11.32.linux_s3

qemu-kvm.git commit and tag:

02/07 11:05:01 INFO | kvm_utils:0367| Commit hash for git://git.kernel.org/pub/scm/virt/kvm/qemu-kvm.git is ed880109f74f0a4dd5b7ec09e6a2d9ba4903d9a5 (tag kvm-88-3361-ged88010)

All suspend to ram tests failed for qemu-kvm.git. Here is a relevant
snippet of a log, that shows when the failure happens:

02/07 14:41:36 INFO |kvm_test_u:0060| Logged into guest 'vm1'

qemu.git didn't have such problems, on the very same job.

I am attaching a tarball with the full logs of one failed test. It
includes things like kvm_stat output during test execution. Let me know
whether you need more info to track down the issue.
