Item 4.02      Non-Reliance on Previously Issued Financial Statements or a
Related Audit Report or Completed Interim Review

               The Board of Directors (the "Board") of Vitesse Semiconductor
Corporation (the "Company") determined on April 26, 2006 that the Company's
previously reported financial statements for the three months ended December 31,
2005 and the three years ended September 30, 2005 and possibly earlier periods
should not be relied upon. The Board of Directors also determined that the
Management Report on Internal Control over Financial Reporting as of September
30, 2005 and the Report of KPMG, LLP, the Company's independent registered
public accounting firm, relating to the effectiveness of the Company's internal
controls over financial reporting and management's assessment thereof as of
September 30, 2005, both of which reports are included in the Company's Annual
Report on Form 10-K for the year ended September 30, 2005, should not be relied
upon.

               The Board has appointed a Special Committee of independent
directors to conduct an internal investigation relating to past stock option
grants, the timing of such grants and other related accounting and documentation
issues. In the course of its investigation, issues have arisen relating to the
integrity of documents concerning the Company's stock option grants. Also during
the internal investigation, issues have arisen concerning the Company's
practices in connection with credits issued to or requested by customers (for
returned products or otherwise) and the related accounting treatment, as well as
the application of payments received to the proper accounts receivable. The
Special Committee is reviewing these issues and, pending further investigation,
believes that the Company's accounts receivable and revenues may have been
misstated during certain periods. Whether the Company's accounts receivable and
revenues were misstated and, if so, the extent of such misstatements are still
under investigation.

               The Company's Audit Committee has discussed the matters disclosed
in this filing with the Company's independent registered public accounting firm.
