I think the patch doesn't work :(
When I try to mount a CD over SCSI emulation I get this nice oops:

After that the System is still responsible but a few minutes later I get this 
in a endless loop:
scsi : aborting command due to timeout : pid 30, scsi0, channel 0, id 1, lun 
0 0x28 00 00 00 00 00 00 00 02 00

I've tried
bh->bi_io_vec->bvl_vec[0].*
instead of
bh->bi_io_vec->bvl_vec->*
but I still get this errors
Maybe someone knows more... I don't

Bye
