This article was previously published under Q188303 SYMPTOMS
On systems with some Cirrus-compatible video adapters, Windows NT may
randomly and infrequently stop responding (hang) and report the following
blue screen error message:
STOP 0x00000050 error
PAGE_FAULT_IN_NONPAGED_AREA.
CAUSE
The GDI in Windows NT requires 8-byte alignment on the bitmaps it is
expected to draw on. Cirrus's driver provides 4-byte alignment instead of
8. This may cause problems on some video adapters where output requests are
delivered to GDI.
