           Summary: DPC Latency Checker barfs loading its driver
           Product: Wine
           Version: 1.1.40
          Platform: x86
               URL: http://www.thesycon.de/deu/latency_check.shtml
        OS/Version: Linux
            Status: NEW
          Keywords: download
          Severity: normal
          Priority: P2
         Component: programs
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: dank at kegel.com


This tool loads a driver that just measures "delayed procedure call"
latency, seems like that ought to be supportable.  Currently crashes 
on startup:

$ wine dpclat.exe
wine: Unhandled page fault on write access to 0x00540180 at address 0x78c32af7
