Could you elaborate on the reason for the above bit of code? Is it to cover some thing from the past or is this an on going issue? I.e. will this disappear soon? Is its usage dependent on a particular driver?
Mostly I am interested in this because it may be at the bottom of a VERY elusive bug (4 systems, heavy network load, crash at 22 hours into the test). Please help.
