>Description:
I use Tekram DC-390 SCSI Host Adapter and IBM DORS-32160 Harddisk
Drive.
DORS-32160 S82C have some problem when tag queueing enable,
So tag queueing disable on SCSI BIOS.
But, I cvsuped amd.c rev 1.5 -> rev 1.9, SCSI BIOS setting is ineffectual.
Accordingly, I add fix for cam_xpt.c. Detail is shown below:
(# camcontrol negotiate -n da -u ? -T disable is no effect.)
{
/* Broken tagged queuing drive */
{ T_DIRECT, SIP_MEDIA_FIXED, "IBM", "DORS*", "*" },
/*quirks*/0, /*mintags*/0, /*maxtags*/0
},
>How-To-Repeat:
configuration: use AMD 53c974 based SCSI Host Adapter
and connected IBM DORS-32160 S82C drive.
