Bug Description
Hi
When installing Ubuntu from cdrom (expert or normal Boot-Option),
the cdrom-boots fine and Installer-Menu appears.
Language, Location, Keyboard layout and even "Detect and mount cdrom" too.
But the next menu point "Load installer components from cd-rom" an error message
is shown:
"There was a problem reading data from the CDROM. ..."
On the 4th console (ALT-F4) I can read:
... anna[3853]: grep:
... anna[3853]: /cdrom/
... anna[3853]: : Not a directory
In the shell (ALT-F2):
* ls -l /cdrom/dists
shows, that "local, stable, testing an unstable" are just empty files
instead of symlinks.
When I boot the installed OS (Knoppix 3.1, 2.4.? Kernel)
The CD-ROM is mounted correctly an the symlinks mentioned above are real
symlinks and not just ordinary files.
But in Knoppix hdc (my cdrom-drive) is mounted with the Kernelmodule Options
(hdc=scsi (written in /etc/lilo.conf) )
I also tried to boot Ubuntu with that option (expert hdc=scsi) but there was no
difference.
(I' m not sure if that boot-option is still supportet in kernel 2.6; any idea
what i should use instead?)
I assume that it could be a problem with the "ide_cd" Kernel modules, because
Knoppix 3.1 uses scsi emulation and works fine. I could also install older
Mandrake Linuxes without problems (8.?), but "newer" ones (9.1) failed too.
Here are parts of the output while trying to install Ubuntu:
hcd: ATAPI 24x CD-ROM drive, Revision: 3.20
ide-cd: cmd 0x28 timed out
hdc: DMA interrupt recovery
hdc: lost interupt

ISO 9660 Extensions: Microsoft Joliet Level 3
cdrom-detect: Detected CD 'Ubuntu 4.10 "Warty Warthog" - Preview i386 Binary
(20041020)'
Any idea what i have to do to install Ubuntu?
Please let me know if you need any more informations.
Thanks for the help in advance
Best Regards

Software : Ubuntu Linux 4.10 "Warty Warthog" (20041020) (from "Linuxuser

Kernel : 2.6.8.1-3-386

CD-ROM Drive: Thoshiba XM 180 2B
This has been fixed in Hoary kernels by disabling CONFIG_ IDEDMA_ ONLYDISK (it was hdc/settings' at the shell
supposed to be disabled in Warty, but the change got dropped by mistake). In the
meantime, try typing 'echo "using_dma:0" > /proc/ide/
on alt-f2.
