Affects: kernel-package (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
I bought a new PIONEER DVD-ROM DVD-115 and installed it on my Computer.
After I insert an DVD, “automount” is doing do a good job an opens
nautilus. Now I'm able to browse through all the files but as soon as I
try to open a bigger one (a mp3 for example) the system reads a few
bites and stops.

A “tail -f” on /var/log/syslog will always  dump the same three lines:

Jan 26 21:32:46 localhost kernel: [4295577.062000] ide: failed opcode was: unknown 
Jan 26 21:32:46 localhost kernel: [4295577.062000] hdc: drive not ready for command 
Jan 26 21:32:46 localhost kernel: [4295577.062000] hdc: status error: status=0x58 { DriveReady SeekComplete DataRequest } 


lshw will tell me the following:

*-cdrom:1 
product: PIONEER DVD-ROM DVD-115 
vendor: Pioneer 
physical id: 1 
bus info: ide at 0.1 
logical name: /dev/hdb 
capabilities: packet 


And I use the following kernel:

title Ubuntu, kernel 2.6.12-10-386 
root (hd0,3) 
kernel /boot/vmlinuz-2.6.12-10-386 root=/dev/hde4 ro quiet splash 
initrd /boot/initrd.img-2.6.12-10-386 

I read on some boards that this is an kernel 2.6 bug which will appear
if there is much IO traffic. So for some help I would be pleased:)
