From Bank of America's just-released 10-Q (via Keith McCullough), here's what the company says about repurchase lawsuits:

The Corporation and affiliates, legacy Countrywide entities and affiliates, and legacy Merrill Lynch entities and affiliates have been named as defendants in a number of cases relating to various roles they played in MBS offerings. These cases are generally purported class action suits or actions by individual purchasers of securities. Although the allegations vary by lawsuit, these cases generally allege that the offering documents for more than $375 billion of securities issued by hundreds of securitization trusts contained material misrepresentations and omissions, including statements regarding the underwriting standards pursuant to which the underlying mortgage loans were issued, the ratings given to the tranches by rating agencies, and the appraisal standards that were used in violation of Section 11 and 12 of the Securities Act of 1933 and/or state securities laws. The cases generally allege unspecified compensatory damages and in some instances, seek rescission. The Corporation has previously disclosed some of these matters under other headings, in its 2009 Annual Report on Form 10-K and Quarterly Reports on Form 10-Q for the quarters ended March 31, 2010 and June 30, 2010, including Countrywide Mortgage-Backed Securities Litigation; IndyMac Litigation; Merrill Lynch Subprime-related Matters; and Federal Home Loan Bank of Seattle Litigation.

This is also an interesting chart, showing repurchase requests from the GSEs by vintage:
