Linux kernel 2.6.18 from http://www.aurel32.net/info/debian_arm_qemu.php will get this mismatch. I don't know the real hardware implement inside scsi. I just modify the hardware emulation consist with the linux driver. Because the hardware emulation is not 100% complete and many parts are not implemented, the mismatch issue the interrupt and the ISR work well in real hardware, but not in QEMU. The problem maybe inside the mismatch condition, but I am not familiar with the mismatch handler. The patch can workaround the mismatch condition. Maybe we should improve the mismatch condition.

What makes you think padding the response with zeros is the right thing to do? I think this is a bug elsewhere (maybe in your device driver). Paul
