Hi Tejun,
Is it possible that the DMA workaround for sata_sil and the
Samsung SH-S183A DVD writer was lost for 2.6.24-rc1? I found
this in syslog:

Its difficult to reproduce, though.

No, I don't think we ever had workaround for sata_sil + SH-S183A
combination. Do you have any specific patch/commit in mind?

The failing command is REPORT_KEY. What were you doing when you saw
this error?
Not being reproducible indicates that it's unlikely to be a DMA issue
and more likely a temporary glitch in media recognition.
Thanks.

Sorry, seems that this wasn't send to the mailing list. See private

Were you able to reproduce it? If it actually is the same problem
(ATAPI DMA timing out on data transfers of certain size), it should be
reproducible when you repeat the same thing.
(Cc'ing Alan) Alan, this was one of those weird ATAPI DMA cases which
were fixed by transfer size alignment check in check_atapi_dma(). The
controller is sata_sil, so I don't think it was a controller problem.
Thanks.

I tried several times this morning, but I couldn't reproduce it.
Maybe its really the hardware. I would suggest to put it on hold.
Thanx anyway
