[Bug 459316] Re: Video DVDs: Buffer I/O errors with Pioneer DVD-105S
Hi Christian, This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ . If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report. apport-collect -p linux 459316 Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results. Thanks in advance. [This is an automated message.

[Bug 459316] Re: Video DVDs: Buffer I/O errors with Pioneer DVD-105S
I was wrong. The UDMA speed sensing seems to work like a charm for my
hard disk (which is UDMA33). The Pioneer DVD-ROM even just uses UDMA33,
so may guess that it SHOULD work with a 40-pin connector as well. It
doesn't though!
To further debug the issue I had the following setup:
* primary controller (ata1): attached a 80-pin wire
* secondary controller (ata2): attached a 40-pin wire
Only two (master) devices: Pioneer CD-ROM and maxtor hard disk
A) Setup 1: Maxtor HD on 40-pin: speed-sensed to UDMA25
ata1 / 80-pin on CD-ROM:
ata2 / 40-pin on maxtor:
dmesg has the following regarding general initialization:
[3.098979] ata1: PATA max UDMA/100 cmd 0x1f0 ctl 0x3f6 bmdma 0xa000 irq 14
[3.098985] ata2: PATA max UDMA/100 cmd 0x170 ctl 0x376 bmdma 0xa008 irq 15
follwed by (CD-ROM)

[3.720652] ata2.00: limited to UDMA/33 due to 40-wire cable
[3.736597] ata2.00: configured for UDMA/33
Now, you may say that the limiting works like a charm, however, now -
after some sr* and sd* lines - we have something interesting:

[4.288603] ata2.00: configured for UDMA/25
[4.288621] ata2: EH complete
In other words, UDMA33 doesn't seem to work properly with a 40-pin cable
in this setup even with the hard disk, and it is speed-sensed to UDMA25
with the hard disk.
A) Setup 2: Pioneer DVDon 40-pin used silently with UDMA33

ata2 / 40-pin on Pioneer CD-ROM:

[3.480447] ata2.01: configured for UDMA/33
Very notable: UDMA33 is NOT down-sensed to UDMA25. There is no exception
mask as in setup 1.
Another interesting aspect is that the BIOS bootup screen reports the
PIO 4 transfer mode for the 40-pin / DVD case, and UDMA33 only when an
80-pin cable is used. I will try to find out how a drive tells the
(BI-)OS and the controller what modes it supports, and whether some of
the Flags are ignored by recent Linux's - which is what I suppose.

[Bug 459316] Re: Video DVDs: Buffer I/O errors with Pioneer DVD-105S
Looking at the Linux PATA driver from Linux 2.6.28 (drivers/ata/libata- core.c) suggests that bus speed limits for PATA drives on SATA are applied in ata_dev_configure(), while 40 pin busses supporting only UDMA-33 are detected with ata_id_xfermask() which is not incorporated into ata_dev_configure(). It looks like Linux tries to dynamically adjust the speed, but this does not seem to work properly for some devices on some 40-pin buses. -- Video DVDs: Buffer I/O errors with Pioneer DVD-105S https://bugs.launchpad.net/bugs/459316 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Renamed title, bug 304954 is probably a duplicate. The fix would be to let linux detect a 40-pin cable and use max.

[Bug 459316] Re: Video DVDs: Buffer I/O errors with Pioneer DVD-105S
I could fix the issue by using a 80-pin UDMA-66 cable. In other words: Previous kernel releases (around 2.6.24-something) handled such devices with 40 pin cables, recent ones don't. Maybe this somehow boosts performance for those who have such a cable, but it renders the system unusable for those who don't. This is a real no-go, since in a developing country you can't just exchange hardware like this. The dmesg log suggests that the bus with a 40 pin cable is configured for UDMA 100, while the German Wikipedia suggests [1] that it should use UDMA 33 max. I will rename the bug report appropriately.

Upgrading to the latest mainline release v2.6.31.5 and v2.6.32-rc5 did not help. The additional boot parameters noapic all_generic_ide (as suggested in some forum entries) did not work. I suppose my Elitegroup K7VZA mainboard / Pioneer DVD-105S causes issues systematic issues. It used to be a very cheap mainboard.
