Here's a few that I remember:

Pakistan vs England, Oval 2006 = the Pakistani team's walkout after the umpire accuses Pak players for ball tampering.
--------------------------------------...
India vs Australia, Sydney test 2008 = umpiring under the scanner after some high profile errors.
--------------------------------------...
India vs South Africa, Jo'berg test 2001 = Match referee punishes 6 Indian players for over appealing. The next test match following this had to be declared "unofficial" after Mike Denness was removed.
--------------------------------------...
India vs Sri Lanka, Kolkata, World Cup semi final 1996= Sri Lanka declared the winners before the ending due to rioting crowd.
--------------------------------------...
New Zealand vs Australia = Melbourne ODI, 1981 = infamous underarm last ball by Trevor Chappel when NZ needed 6 runs.
--------------------------------------...
Ireland vs Pakistan, 2007 W.C match= The unfortunate post match events and conspiracy theories put this in the list.
--------------------------------------...
England vs Australia = The 1933 bodyline series.

Can you list any more such incidents?

If not then choose the most controversial from my list.
Update: ah thanks madcap for adding another match. I hope you guys come up with more such incidents. I'm really curious to enhance my knowledge.
Update 2: oops Port Elizabeth it was, not Jo'berg . Thanks Oracle.
