This can be interpreted by using linux/scsi/scsi.h. The suggestion byte
0x20 is SUGGEST_ABORT, the driver code 0x07 (suggestion and driver code
are packed into one byte), and the host byte 0x07 is DID_ERROR. This means
that the Buslogic driver encountered an internal error. Further
interpretation can be found by looking at linux/drivers/scsi/Buslogic.c.
There are many conditions that return DID_ERROR. Some of those are related
to SCSI bus error conditions but there are also errors related to the host
adapter software and the driver.
The standard suggestion is: check your cables, termination, and SCSI
address assignments.
