On Dell PE6450 with CD or DVD drives (IDE) install fails with simmilar
CD> VT1 reports:
"failed to read /modules/module-info
install exited abnormally

/mnt/source umount failed(16)

exec of /bin/sh failed

DVD> fails to launch X, but makes it into text mode. Allows specification
of Language and Keymap but then prompts for installation media type. When
CD is chosen, mount fails and you are prompted again.
VT4: <4>Unable to identify CD-ROM format
Steps to Reproduce:
1.On PE6450 (probably all Dell IDE CD/DVD systems)
Try and perform CD install
2.Just wait until kernel boots, then check out VTs.
I should add that the same media works fine on SCSI CD-ROM systems. Also BETA2
and 7.0 load properly, I don't know about BETA3. This must be something that
We (Red Hat) should really try to resolve this before next release.
There are no other types of kernel errors messages on VC4?
msf, I have a machine you can test on
On an installed system, I can mount /mnt/cdrom and copy files just fine. That
would contain this problem to install time.
johnsonm - is this still an issue we need to look at, or is it fixed?
This is still a problem. Only now IDE CD-ROM behaves like the DVD did in RC1. I
have not checked with the DVD yet. I will do that in the morning and let you
know if anything changes. Also, the X-based installer will not work on this
machine, it only goes into text mode - I dont remember if I mentioned that
this appears to be DMA corruption problems with this controller/CD-ROM device.
Could you give me the output of
(replace X with hda/hdb/hdc/hdd for the cdrom/dvd drive)
SAMSUNG CD-ROM SN-124
This is on a RC1 machine. The same CD and DVD drives work fine with 7.0 and I
believe Beta2 or 3.
Please test 2.4.2-0.1.23 or later kernels; we have added a
special case to attempt to handle this hardware.
