Description:
Upgrading to kernel 2.6.24.2 made using cdrom drive impossible.

Additional info:

Output from dmesg:

Every read operation results in buffer i/o errors. I've tried with every possible kind of media, it always end up with a large amount of errors. Even burning cd/dvd has become impossible. Of course, using an old 2.6.23.9 kernel makes everything work fine as usual. I've also tried using a vanilla kernel, with the same results.

Maybe the problem is this http://bugzilla.kernel.org/show_bug.cgi?id=9178, could you
give an output of dmesg, showing the CD-ROM detection part.
Comment by Marco (grishnack) - Sunday, 24 February 2008, 07:30 GMT-4
No, the cdrom worked fine with 2.6.23.9.

Actually, Since I upgraded the kernel the other day, no /dev/sdx devices are being created. All my pata drives show up as /dev/hdx again, which kinda sucks because the machine is setup to boot from an sd device. Something must have gotten messed up in the pata drivers. As soon as I did the upgrade, I went to reboot and the machine would not start.
Comment by Ray Rashif (schivmeister) - Wednesday, 19 March 2008, 10:56 GMT-4
It may have something to do with SCSI emulation of Optical Drives, particularly burners. I don't quite know since when the emulation is no longer required, it may just be old news.

If you autodetect modules, the disabling of the emulation may have triggered the kernel to recognize the rest of the kernel as IDE/PATA unless explicitly told otherwise.
Comment by Justin H (orasis) - Monday, 24 March 2008, 03:18 GMT-4
I've had this problem as well - comment out the Cdrom device (/dev/sr0 usually) in /etc/fstab; that solved the problem for me. (Yes Arch will still see your Cdrom and mount it auto and all of that good stuff.)

Hope it works for you.

Comment by Marco (grishnack) - Tuesday, 25 March 2008, 04:46 GMT-4
Nope, it didn't work.
Comment by Mika Hynnä (ighea) - Tuesday, 25 March 2008, 16:56 GMT-4
So you still don't have any sgX or scdX nodes in /dev/ even with the latest kernel?
Comment by Marco (grishnack) - Tuesday, 25 March 2008, 17:42 GMT-4
scd0 is a symlink to sr0, so it is quite useless. I've got sgX nodes too, but how should i use them?
Comment by Mika Hynnä (ighea) - Tuesday, 25 March 2008, 17:44 GMT-4
So you should have cdrom and cdrw nodes too?
Comment by Marco (grishnack) - Tuesday, 25 March 2008, 19:34 GMT-4
Yes, i have them both.
Comment by Mika Hynnä (ighea) - Tuesday, 25 March 2008, 19:58 GMT-4
You could try kernel parameters all_generic_ide and/or ide=nodma to see if they help. This seems to be common problem and is also discussed in here https://bugs.launchpad.net/ubuntu/+source/linux/+bug/181561 .
Comment by Marco (grishnack) - Wednesday, 26 March 2008, 04:48 GMT-4
Nothing yet, i tried both options but to no avail. It seems to be an hardware specific problem, but the common workarounds don't seem to work for my hardware.
Comment by Fabian Hirschmann (firsm) - Wednesday, 26 March 2008, 13:05 GMT-4
It might also be related to http://bugzilla.kernel.org/show_bug.cgi?id=9370
I'm having similar problems with the current -ARCH:

Buffer I/O error on device sr0, logical block 3609348
attempt to access beyond end of device
sr0: rw=0, want=14437400, limit=2097151
Buffer I/O error on device sr0, logical block 3609349
attempt to access beyond end of device
sr0: rw=0, want=14437404, limit=2097151
Buffer I/O error on device sr0, logical block 3609350

However, according to the kernel bugzilla it seems to be fixed in the current git.
Comment by Marco (grishnack) - Wednesday, 26 March 2008, 14:57 GMT-4
I don't think that's the same issue. The problem (i guess) is related to the particular combination of controller and drive. The driver issues requests to the device, but it always returns errors. The strange thing is that the TOC is accessed correctly, so maybe the problem is located in the filesystem.
Comment by Dan McGee (toofishes) - Saturday, 26 April 2008, 11:15 GMT-4
2.6.25 status?
Comment by Taylor Lookabaugh (Taylor) - Saturday, 10 May 2008, 11:27 GMT-4
It is still broken to this point, I wonder what's causing the sd_mod module not to work properly
