I reproduced the hang that happens after (otherwise successful) hibernation. After a second hibernation & resume I reproduced the mysterious call-traces.
I posted this information, a full system log (including 2 hibernation cycles and the calltraces), and the kernel config to the bugzilla entry.
This was in response to Rafael's request on the bugzilla. So I expect someone will look at it anyway, but I thought I should copy you on this.
