Soft lockup with hibernate in 3.10

Hi all,

I just started using 3.10 and I'm getting soft lockups on resume. After
resume, kworker becomes a hung task and any other attemps to hibernate
fail. Here is the stack trace:

[ 1200.746623] INFO: task kworker/0:1:5738 blocked for more than 120

Does anyone have the same problem? I'm using the hibernate script to
perform my suspend / resume.
