Package: linux-image-3.2.0-4-686-pae Version: 3.2.51-1 Severity: normal With the standard wheezy kernel, suspend fails:

I tried upgrading to linux-image-3.11-0.bpo.2-686-pae from wheezy-backports, and suspend with that kernel works just fine. Googling turned up <https://bugzilla.kernel.org/show_bug.cgi?id=16256>. Sure enough, unloading the tpm_tis module allows suspend to work: [ 339.014601] PM: Syncing filesystems ... done.
