ata2.00: failed to set xfermode (err_mask=0x4) since 2.6.36

Hi,
I'm getting the above message while booting since updating the kernel to the 2.6.36.
dmesg sais:

ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
ata2.00: ATAPI: PIONEER DVD-RW  DVR-212D, 1.28, max UDMA/66
ata2.00: qc timeout (cmd 0xef)
ata2.00: failed to set xfermode (err_mask=0x4)

ata2.00: failed to set xfermode (err_mask=0x4)
ata2: limiting SATA link speed to 1.5 Gbps
ata2.00: limiting speed to UDMA/66:PIO3
ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 310)
ata2.00: qc timeout (cmd 0xef)
ata2.00: failed to set xfermode (err_mask=0x4)
ata2.00: disabled
ata2: hard resetting link
ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 310)
ata2: EH complete

Obviously, the DVD burner is not working.
Can anyone help me?

Regards

You seem to have the same exact problem as reported here

This problem was fixed with this patch:

This patch is already applied to the 2.6.36 kernel though.

Judging by that part of the patch (look at that its a Pioneer drive also like yours ) the fix is only applied to that certain drive sooo adding your drive to the list there should allow it to use "ATA_HORKAGE_NOSETXFER" as well; which fixed the other persons problem.

SO what I'm saying is I made up a patch to add your drive to the above list. You can try it out if you want.

My patch is pretty simple and makes sense to me..

I don't think tpowa the kernel mantainer is lurking here , you can try to open a bug report on flyspray with the patch. Surely he knows
how to handle it upstream if it's necessary...

Re: ata2.00: failed to set xfermode (err_mask=0x4) since 2.6.36

Six months later and the patch still didn't make it upstream. I'm having the same problem with another Pioneer unit (surprise) and commented about it on the flyspray bug opened by whaevr, but got no response so far...
