Message-ID: <20040325153631.GA4456@beardog.cca.cpqcorp.net> (raw)
Please consider this change for inclusion in the 2.4 kernel.
This change is required to support the new MSA30 storage enclosure.
If you do a SCSI inquiry to a SATA disk bad things happen. This patch prevents
the inquiry from going to SATA disks.
