Changes (by audiotoaster):

 * resolution:  needs_more_info => invalid


Comment:

 Turns out corruption was caused by faulty DRAM.

 Just enough to cause corruption of output yet not sufficient to raise
 errors in 24hr burnin test.

 After replacing all DRAM two months have passed without noticing a single
 output corruption issue.
