SYMPTOMS
During DVD playback on an Intel ICH6-based computer, the computer may stop responding (hang). The clock and the mouse pointer still work, but all other programs stop responding, including the desktop. This problem occurs on heavily stressed computers where much concurrent traffic moves across the ATA and USB 2.0 buses during DVD playback.



CAUSE
This problem occurs because the cache manager dirty page threshold is exceeded. Therefore, the cache manager cannot accept any more writes to the hard disk drives.
