Comment 22 for bug 1927545

Here what I was able to extract with the latest kernel:

Fn+F4
[ 44.615947] lenovo_raw_event data 0x1:0x0:0x0
[ 44.615950] report id/type/app: 1/0/786433 maxfield: 1
[ 44.615952] field 0 physical: 0x000000 logical 0x000000 app 0x0c0001 flags 0x000000, max usage 573
[ 44.615953] usage 0 hid: 0x0c0000 index 0x000000 code 0x00 type 0x0

Fn+F10
[ 51.971153] lenovo_raw_event data 0x1:0x0:0x0
[ 51.971183] report id/type/app: 1/0/786433 maxfield: 1
[ 51.971185] field 0 physical: 0x000000 logical 0x000000 app 0x0c0001 flags 0x000000, max usage 573
[ 51.971188] usage 0 hid: 0x0c0000 index 0x000000 code 0x00 type 0x0

After pressing fn+Fx keys keyboard and mouse stopped to work and last line in logs above was printed forever.
