[Bug 1450813] [NEW] Regression in mei_me.ko for 3.13.0-51

 

Public bug reported:

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
[ 6.355714] mei_me 0000:00:16.0: reset failed
[ 6.355716] mei_me 0000:00:16.0: link layer initialization failed.
[ 6.355717] mei_me 0000:00:16.0: init hw failure.
[ 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.
