Subject: cdromaudio patch gives up too easily
Date: Tue, 09 Mar 2004 14:07:23 +0000 [thread overview]
Message-ID: <1078841242.995.24.camel@newt> (raw)
The patch for DMA based CD reading worked well for me until I tried to
read the audio from a badly damaged CDR. At this point the code dropped
back to the old mechanism and stayed that way for further CDs.
The logs below show what happened, running 2.6.4-rc2 with just that
patch:
cdrom: open failed.
hdc: packet command error: status=0x51 { DriveReady SeekComplete Error }
hdc: packet command error: error=0x30
ATAPI device hdc:
Error: Medium error -- (Sense key=0x03)
(reserved error code) -- (asc=0x57, ascq=0x00)
The failed "Prevent/Allow Medium Removal" packet command was:
"1e 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 "
cdrom: open failed.
hdc: packet command error: status=0x51 { DriveReady SeekComplete Error }
hdc: packet command error: error=0x30
ATAPI device hdc:
Error: Medium error -- (Sense key=0x03)
(reserved error code) -- (asc=0x57, ascq=0x00)
The failed "Prevent/Allow Medium Removal" packet command was:
"1e 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 "
cdrom: cdda rip sense 03/02/00
cdrom: dropping to old style cdda
hdc: packet command error: status=0x51 { DriveReady SeekComplete Error }
hdc: packet command error: error=0x30
ATAPI device hdc:
Error: Medium error -- (Sense key=0x03)
(reserved error code) -- (asc=0x02, ascq=0x00)
The failed "Read CD" packet command was:
"be 04 00 00 00 00 00 00 08 f8 00 00 00 00 00 00 "
... and the above pattern eventually becomes this:
ide-cd: cmd 0xbe timed out
hdc: irq timeout: status=0xd0 { Busy }
hdc: irq timeout: error=0xd0LastFailedSense 0x0d
hdc: ATAPI reset complete
ide-cd: cmd 0xbe timed out
hdc: irq timeout: status=0xd0 { Busy }
hdc: irq timeout: error=0xd0LastFailedSense 0x0d
hdc: ATAPI reset complete
ide-cd: cmd 0xbe timed out
hdc: irq timeout: status=0xd0 { Busy }
hdc: irq timeout: error=0xd0LastFailedSense 0x0d
hdc: status timeout: status=0xd0 { Busy }
hdc: status timeout: error=0xd0LastFailedSense 0x0d
hdc: drive not ready for command
hdc: ATAPI reset complete
At some point in the sequence I killed grip and ejected the CD.
