Hm...  All strategy does is try to read a single block from the disk.
It's trying to read 0x800 bytes from 0x144 blocks in and deposit the
results at address fff73ff0.  It returns the amount read, which in this
case is 0, so it failed.  Could you try to debug strategy?  It appears
that the read operation on the disk is not succeeding.
