I'm not sure if it is the same problem, but I was having problems with
Cygwin on my new Dell D820.  I uninstalled some (non-cygwin) software and it
started working.  I recently had an email from someone else with similar
issues and passed on my experience.  They found the culprit to be the
Embassy Trust Suite (or whatever its called - the software for the
fingerprint reader).  Getting rid of that allowed cygwin to work normally.

HTH,

Steve
