Hi,
The attached DMP file is of the UNEXPECTED_KERNEL_MODE_TRAP (7f) bug check.
This bug check indicates that the Intel CPU generated a trap and the kernel failed to catch this trap.
BugCheck 7F, {8, ffffd0014a76e130, ffffd0014a774fe0, fffff800b6d4b6ca}
The 1st parameter of the bug check is 0x00000008, or Double Fault, indicates that an exception occurs during a call to the handler for a prior exception. Typically, the two exceptions are handled serially. However, there are several exceptions that cannot be handled serially, and in this situation the processor signals a double fault.

It appears the VIA_USB_SER.sys driver is causing problems here. I am unsure as to what this driver is, perhaps a USB to Serial adapter, or vice-versa? I'd remove it ASAP device-wise as well as uninstall the software.

Patrick
