The Windows 8.1 upgrade has installed version 184.108.40.2060 of the Intel graphics driver on my Clover Trail tablet (a Lenovo ThinkPad Tablet 2).
This driver often (8 times out of 10?) crashes when the tablet comes out of Connected Standby. In the System Event log, a warning "Display driver igdkmd32 stopped responding and has successfully recovered" with the ID 4101 is recorded each time this occurs.
Occasionally, the driver fails to restart and a hard reboot is necessary.
Looking around the manufacturers' support forums, I see this issue being reported on other brands of Intel Clover Trail tablets, so it is not a Lenovo issue, but rather a Microsoft/Intel issue.
When is a new driver expected that will fix this issue?
