this bugcheck Bug Check 0x4E: PFN_LIST_CORRUPT
with suberror code 0x9a indicates that a driver attempted to free a page of memory while the page is still locked for input output. (in use)

That would be a bug in the driver. It could also be caused if another driver corrupts the first drivers data.

if you put the memory .dmp file on a server and post a link here someone might be able to look at the binary with a debugger and tell you what driver to update.
