Summary: can't watch dvd using pata-ali or ata-generic
Product: SCSI Drivers
Version: 2.5
Kernel Version: 2.6.35
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Other
AssignedTo: [email protected]
ReportedBy: [email protected]
Regression: No

I'm trying to use my old toshiba laptop with more recent kernels to watch dvd's and the dvd is jerky and drops frames. Basically unusable.

I have an older ubuntu 8.04.4 with the older kernel 2.6.24 that plays fine. It uses the older ide-core / ata-generic series kernel modules.

I have tried to upgrade to newer versions of ubuntu, and all fail to be able to watch dvd's. All use the newer pata-ali kernel module.

I recently tried the 2.6.35-9 kernel and have the same bad experience with the pata-ali module. Here's the relevent dmesg messages:

I found a bug report at ubuntu (#228302) where other people had tried blacklisting the pata-ali module and using the ata_generic instead. I wanted to try this to see if dvd playback would improve, but could not get it to work.

The bootup took a lot longer than normal, and when I tried to access the dvd, it failed with a time out message. I could not get it to mount or to play dvd's under mplayer or other player software.

When I booted up with the ata_generic enabled, I noticed these ata related messages:

My questions are:

1. Is there something else I can try to get better ata performance on newer linux kernels (so I can watch dvd's)?

2. If I'm supposed to use the ata_generic module, how can I deal with the message "Consider BLIST_INQUIRY_36 for this device" and get it working.

If you need more information about my hardware, I can supply it. Let me know. Following is the lspci -vvv and lspci -n output:

Summary: can't watch dvd using pata-ali or ata-generic
Product: SCSI Drivers
Version: 2.5
Kernel Version: 2.6.35

I'm trying to use my old toshiba laptop with more recent kernels to watch dvd's and the dvd is jerky and drops frames. Basically unusable.

I have an older ubuntu 8.04.4 with the older kernel 2.6.24 that plays fine. It uses the older ide-core / ata-generic series kernel modules.

I have tried to upgrade to newer versions of ubuntu, and all fail to be able to watch dvd's. All use the newer pata-ali kernel module.

I recently tried the 2.6.35-9 kernel and have the same bad experience with the pata-ali module. Here's the relevent dmesg messages:

I found a bug report at ubuntu (#228302) where other people had tried blacklisting the pata-ali module and using the ata_generic instead. I wanted to try this to see if dvd playback would improve, but could not get it to work.

The bootup took a lot longer than normal, and when I tried to access the dvd, it failed with a time out message. I could not get it to mount or to play dvd's under mplayer or other player software.

When I booted up with the ata_generic enabled, I noticed these ata related messages:

My questions are:

1. Is there something else I can try to get better ata performance on newer linux kernels (so I can watch dvd's)?

2. If I'm supposed to use the ata_generic module, how can I deal with the message "Consider BLIST_INQUIRY_36 for this device" and get it working.

If you need more information about my hardware, I can supply it. Let me know. Following is the lspci -vvv and lspci -n output:

Summary: can't watch dvd using pata-ali or ata-generic
Product: SCSI Drivers
Version: 2.5
Kernel Version: 2.6.35
Platform: All
OS/Version: Linux
Tree: Mainline

I'm trying to use my old toshiba laptop with more recent kernels to watch dvd's and the dvd is jerky and drops frames. Basically unusable.

I have an older ubuntu 8.04.4 with the older kernel 2.6.24 that plays fine. It uses the older ide-core / ata-generic series kernel modules.

I have tried to upgrade to newer versions of ubuntu, and all fail to be able to watch dvd's. All use the newer pata-ali kernel module.

I recently tried the 2.6.35-9 kernel and have the same bad experience with the pata-ali module. Here's the relevent dmesg messages:

I found a bug report at ubuntu (#228302) where other people had tried blacklisting the pata-ali module and using the ata_generic instead. I wanted to try this to see if dvd playback would improve, but could not get it to work.

The bootup took a lot longer than normal, and when I tried to access the dvd, it failed with a time out message. I could not get it to mount or to play dvd's under mplayer or other player software.

When I booted up with the ata_generic enabled, I noticed these ata related messages:

My questions are:

1. Is there something else I can try to get better ata performance on newer linux kernels (so I can watch dvd's)?

2. If I'm supposed to use the ata_generic module, how can I deal with the message "Consider BLIST_INQUIRY_36 for this device" and get it working.

If you need more information about my hardware, I can supply it. Let me know. Following is the lspci -vvv and lspci -n output:

[Bug 16449] can't watch dvd using pata-ali or ata-generic

--- Comment #2 from Ben Kibbey <[email protected]> 2010-08-14 22:44:38 --- I have this problem too. I was using the deprecated ATA modules without problems. After switching to the pata-ali driver though the DVD consumes 100% CPU. A normal IDE HDD with the pata-ali module seems to work fine.
