Right; The issue isn't theoretical, it was seen and reported by Mr Qinghao, CC'd here. | Maybe real hardware will run an endless loop? | Or the "endless" loop is terminated because the driver | changes the link while the loop is running? IIUC, command execution loop is terminated when 'I', 'EL' or 'S' bits are set in the current command block, otherwise loop continues to read the next command block(CB) in the list. -- - P J P 47AF CE69 3A90 54AA 9045 1053 DD13 3D32 FE5B 041F
