Subject: [PATCH 051/109] intel_ips: blacklist HP ProBook laptops
|
|
|
|
commit 88ca518b0bb4161e5f20f8a1d9cc477cae294e54 upstream.
|
|
|
|
intel_ips driver spews the warning message
|
|
"ME failed to update for more than 1s, likely hung"
|
|
at each second endlessly on HP ProBook laptops with IronLake.
|
|
|
|
As this has never worked, better to blacklist the driver for now.
