Hello. I have been getting a couple of BSODs lately and i used driver verifier and found out that it is caused by L1C63x64.sys. I have already updated my Atheros Lan driver to the latest version but i'm still getting this BSOD. Qualcomm Atheros AR8171/8175 PCI-E Gigabit Ethernet Controller (NDIS 6.30).
I have attached the minidump file.
Thanks

The windows 8.1 driver from Lenovo names the following version and date 2.1.0.21
10/16/2013

To be sure you have the latest version and your current version is not corrupted i would uninstall the current driver and reinstall the above windows 8.1. driver.
