Hello nic,
we are a small company in germany selling mini-pcs based on intel hardware.
We have a problem with windows crashing (bsod) when unplugging HDMI / Displayport
and connecting again. At first there is the error:
"Display driver igfx stopped responding and has successfully recovered"
But when unplugging and plugging again 2-3 times Windows is crashing. Sometimes
it crashes at the first time unplugging HDMI / Displayport:
BugCheck 116, {fffffa80076314e0, fffff88004e4a540, 0, d}
Probably caused by : igdkmd64.sys ( igdkmd64+1d540 )
MODULE_NAME: igdkmd64
IMAGE_NAME: igdkmd64.sys
We tried to narrow down the problem without success:
1) Unplugging / Plugging works on Ubuntu!
2) We tried different boards (on 3 ASUS Q87T)
3) We tried different memory
4) We tried several BIOS-settings related to the iGPU
5) We tried several BIOS-versions
6) We tried Windows 7 x64 und Windows 8.1 x64 (same effect on both)
7) We tried different Driver-Versions (3345, older version on intel site + driver from ASUS)
Any idea why this happens? It drives me crazy ...
Best regards,
Felix
