[Help Me]Only backlight when wake up from sleep.

[Pyeh]

Hi，everyone. My machine has some problems in 10.12.4, 10.12.5 and 10.12.6.
ASUS-A555LF
CPU: i5-5200, HD5500 (1920x1080, 15.3 inch)

Begin from 10.12.4, the screen doesn't show anything when wake up from sleep，only backlight

10.12.3: ig 0x16260006 ,everything work well .
10.12.4: 0x16260006 has broken, doesn't work too.(only backlight)
I think the matter is about the AppleIntelBDWGraphicsFramebuffer.kext

10.12.6-IOR is from the system 10.12.6, it has the screen problem.
10.12.3-IOR is from the system 10.12.3, it is normal.

Compare ig-platform-id data in 10.12.3 and 10.12.6.
Maybe something is changed that can be patched.

Thanks for your reply.
I search 06002616，I found this part(10.12.3) is same as 10.12.6
{06002616 01030303 00002002 00005001
00000060 D90A0000 D90A0000 00000000

00000000 05000000 00000000 04000000}

and I search 06002616 again ，I found some different
at the part ：
{ //at 10.12.6

00008138 06002616 741648FF 05CF2011
00498B87 B8170000 81380500 26167511
}
{//at 10.12.2（I feel 10.12.2 is more current than 3）

00498B87 B0170000 81380600 26167416
48FF0539 39100049 8B87B017 00008138
}
but，I don't know what this part means，
so I make a patch about this part
Find: 06002616 741648FF 05CF2011 00498B87 B8170000
Replace: 0600 26167416 48FF0539 39100049 8B87B017 0000
However ,it didn't show change anything for the issue.

You're only showing a portion of the data.
ig-platform-id entries in BDW are 136 bytes.

and I search 06002616 again ，I found some different
at the part ：
{ //at 10.12.6
DE000000 48FF05D5 20110049 8B87B817

48FF0539 39100049 8B87B017 00008138
}
but，I don't know what this part means，

That data is not part of the ig-platform-id data.
It is probably code.
You can find out more by looking at a disassembly listing.

so I make a patch about this part
Find: 06002616 741648FF 05CF2011 00498B87 B8170000
Replace: 0600 26167416 48FF0539 39100049 8B87B017 0000
However ,it didn't show change anything for the issue.

Such a patch is a bad idea anyway.
Code patches must be crafted carefully after analysis of the disassembled kext.

ig-platform-id entries in BDW are 136 bytes.

Sorry,I have no idea how to do that.
I search "06002616" at BDW ,only find two places.
Do you mean the “entries” is this part？

{06002616 01030303 00002002 00005001
00000060 D90A0000 D90A0000 00000000
00000000 00000000 00000800 02000000
30020000 01050B00 00040000 07050000
02040B00 00040000 07050000 FF000000
01000000 40000000 0B0B0000 01010500
00000000 05000000 00000000 04000000}

but I found more data（followed 06002616） both are the same

The 06002616 01030303 is the start of the ig-platform-id data for 0x16260006.
But the data there is 136 bytes.
You can tell by looking where the next ig-platform-id starts (0x162b0008).

@Pyeh did you managed to fix this? i have the same problem (and many more users as far as I can see that have intel 5500)
