Subject: Failed to set xfermode on LITE-ON  LTR-40125S
Date: Thu, 25 Jan 2007 20:17:50 +0000	[thread overview]
Message-ID: <20070125201750.2adbd57c@buffy.scoobygang> (raw)

Hello,

I just tried the libata support for PATA in kernel 2.6.20-rc5 and I got
this:

scsi1 : pata_sis
ata2.00: ATAPI, max UDMA/66
ata2.01: ATAPI, max UDMA/33
ata2.00: configured for UDMA/33
ata2.01: qc timeout (cmd 0xef)
ata2.01: failed to set xfermode (err_mask=0x4)
ata2.01: limiting speed to UDMA/25
ata2: failed to recover some devices, retrying in 5 secs
ata2.00: configured for UDMA/33
ata2.01: qc timeout (cmd 0xef)
ata2.01: failed to set xfermode (err_mask=0x4)
ata2.01: limiting speed to PIO0
ata2: failed to recover some devices, retrying in 5 secs
ata2.00: configured for UDMA/33
ata2.01: qc timeout (cmd 0xef)
ata2.01: failed to set xfermode (err_mask=0x4)
ata2.01: disabled
ata2: failed to recover some devices, retrying in 5 secs
ata2.00: failed to set xfermode (err_mask=0x40)
ata2.00: limiting speed to UDMA/25
ata2: failed to recover some devices, retrying in 5 secs
ata2.00: configured for UDMA/25

The offending device is a LITE-ON LTR-40125S CDRW attached to SIS 513
IDE (rev d0)

I found a patch here:
http://readlist.com/lists/vger.kernel.org/linux-kernel/45/228948.html
which cures the problem for me. Is this the recommended patch for this
problem? If not, I would be happy to test alternative solutions.

Thanks,
John Williams
