Bug#265747: more info on hangs with Cyberdrive and VIA chipset.
This is definitely a Linux Kernel bug! It is obvious that a ioctl() that hangs (does not return) although it has been given a timeout is the evidence for a kernel bug.

Bug#265747: more info on hangs with Cyberdrive and VIA chipset.
Hello. I disabled the rezero_unit but didn't change anything, I reenabled it and disabled the get_dmaspeed. This time I can write from the command line and from XCDRoast too! Maybe the get_dmaspeed makes this drives go crazy, it would be nice to have a way to disable it in runtime, without needing to recompile cdrecord. Or maybe just disable it by default... I wonder why it is useful nowadays since drives have underrun protections. I have a cdrecord package with the get_dmaspeed thing disabled, if someone doesn't want to recompile the package I can send the .deb (just dpkg -i it). Please, can someone else test without the get_dmaspeed thing to see if it fixes its problems and post results (either succesful or not)? If I am not the only one then some solution could be considered... Thanks for your times!

>I hate to report that Windows XP with Nero works without problems, >but is not my favorite OS. Could you tell if windows have disabled dma automatically ? Once you know the "ide controller" your cdrom is bound to (see the note at the end of the mail): - open Device Manager > IDE ATA/ATAPI Controller, select the wanted controller. - open its "properties" window and switch to "advanced settings" tab. There you have two "device data" group (0 and 1). I do not know how to find which one related to the cdrom (here I only have the cdrom on the "secondary ide channel" so it is the entry with a "current transfer mode"). please gives us the "current transfert mode". I have "ultra DMA mode 2" here (only as reference, the bug does not show up on this box). This means DMA is enabled. Greetings. Alban PS: you could try latest >= 2.6.14-rc3* kernels if your are easy with compiling a the kernel. The reimplementation of the "IDE" code is mostly complete nows (this is/was the biggest remaining "not so good" code in linux). I do not have access to the box I own which have the "broken" cdwriter before monthes. I highly expect your results (even if only the windows behaviour - disabling the dma or relying on via to provide a driver with an unknown trick to work well even with the hardware behaving badly). --- "HOWTO find the IDE Controller the cdrom is bound" ... to without opening the box and knowing about pc internals. - linux : if your cdrom is on the first ide connector it is bound tohda or hdb - windows : Device Manager > IDE ATA/ATAPI Controller the open "properties" window for each IDE controller and switch to "details" tab. In the list choose "Bus relations" and you will see a name. This name is in "device manager" cdrom list. ___ Appel audio GRATUIT partout dans le monde avec le nouveau Yahoo!

Bug#265747: more info on hangs with Cyberdrive and VIA chipset.
Package: cdrecord
Version: 4:2.01+01a01-4
Followup-For: Bug #265747
I was going to write the following bug report and I found this one that seems
the same, but I still submit my information, maybe it helps.
Cdrecord-Clone 2.01.01a01
Linux 2.6.12.5
Debian Testing of 1 september 2005.
Cdrecord freezes, I can't write CDs.
I tried diferent transports: ATA, ATAPI, /dev/hdc, and even ide-scsi, they all
freeze.
I hate to report that Windows XP with Nero works without problems, but is not
my favorite OS.
I tried Knoppix 3.6 too, both with 2.4 and 2.6 kernels and it doesn't work
too, the Debian package kernel-image-2.6.8-2-k7 version 2.6.8-16 doesn't work
neither.
I want to be as helpful to you as I can, so tell me what to do and I will do
it, I appreciate your help.
I use Linux since 1996 and I never had problems with CD writing.
The same CD Writer works on my old computer, I buyed a new one but keeped my
old CD Writer.
Yes, I know that I don't have the best brands of hardware, but they are more
expensive and I live in the 3rd. world, though it works on Windows so hopefuly
it could work on Linux.
The kernel complains in multiple ways, sometimes it simply says several times:
hdc: lost interrupt
and other times it says all this:
hdc: drive_cmd: status=0x51 { DriveReady SeekComplete Error }
hdc: drive_cmd: error=0x04 { AbortedCommand }
ide: failed opcode was: 0xec
hdc: status timeout: status=0xd0 { Busy }
ide: failed opcode was: unknown
hdc: DMA disabled
hdc: drive not ready for command
hdc: ATAPI reset complete
hdc: request sense failure: status=0x51 { DriveReady SeekComplete Error }
hdc: request sense failure: error=0x50 { LastFailedSense=0x05 }
