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.
