The patch you had is actually insufficient for the problem. Attached is a
test patch I put together. It does the obviously correct things in regards
to scsi_allocate_device(), scsi_release_device(), scsi_free(), and
scsi_malloc(). However, I don't think this patch does *all* that it needs
to do, but it might. Give it a try and see if things work any better.
