Fault occurs while handling a fault
—
Task switch to an invalid segment
Instruction loads a segment and present bit is 0 (invalid segment)
Stack operation causes limit violation or present bit is 0
Segment related or miscellaneous invalid actions
Page protection violation or a reference to missing page
Arithmetic error generated by floating-point instruction
Data reference to an unaligned operand. (The AC flag and the AM bit of CR0 are
set to 1.)
