Dear Jeff,
I was looking at the kernel 2.6.21 code of the achi driver and found
that the sg_table_size was set to 168, while the libata set the maximum
sg to be 128 somewhere else. When a requester issues a request with >128
sgs to the ahci attached device, the system would fall to a scilent
error. So, I could not count on the scsi probe
of scsi_device->->host->sg_tablesize that was read from achi.
Any advise on the better fix?
Thanks you very much,
Can you be more specific about "somewhere else"?
Reducing s/g table size should be quite safe.
Jeff
