[Bug 1450813] Re: Regression in mei_me.ko for 3.13.0-51
here are my test results:
3.13.0-51 without fa90035 and without e301eaa => init ok
3.13.0-51 without fa90035 => init ok
3.13.0-51 without e301eaa => init error
3.13.0-51 => init error
So problem is really caused by commit fa90035.

Bug description:
After upgrading linux-image-3.13.0-49-generic to linux-
image-3.13.0-51-generic I started getting this error message in dmesg:
[ 6.352555] mei_me 0000:00:16.0: irq 47 for MSI/MSI-X
[ 6.355708] mei_me 0000:00:16.0: version message write failed: ret = -5
[ 6.355712] mei_me 0000:00:16.0: hbm_start failed ret = -5

[ 6.355880] mei_me 0000:00:16.0: initialization failed.
Downgrading back to linux-image-3.13.0-49-generic fixed this problem.
So this is regression for version 3.13.0-51.
