Installation - Internal Error

Description of Problem:Installation process failed during formatting of
Steps to Reproduce:
Created attachment 21686 [details]
File dumped from installation process.
What are the steps required to reproduce this behavior?
I have two hard drives (hda and hdb) and a cdrom (hdc). I have not been able to
convince the installation process to talk to the cdrom. It finds it at hdc and
detects its nature (32x cdrom) but when it tries to read it, errors result and
it hangs. Windows recognizes it as a generic NEC cdrom. To bypass this problem
I had copied the cdrom images to hdb and used the 'linux expert' command to
install from the images. My root partition is on hda. I tried to install and
the disk driver produced a multitude of errors- disk busy errors, timeouts and
controller resets. The installation failed part way through the installation of
packages and the machine rebooted. I then restarted the installation in the
same way and it failed when it tried to start the formatting of the root
partition. This resulted in the internal error message with a request to submit
it to bugzilla. I have subsequently deduced that the disk driver does not take
kindly to alternate operations on the master and slave drives on the same IDE.
In this case reads from hdb and writes to hda. I then moved the cdrom images
to hda and my installation completed with no problems. Windows has no problem
with such operations so I assume it is in Linux. I have similar problems with
my Linux kernel 2.0.25.
Try making a boot disk with the boot.img file in the /images directory on the
cdrom. Boot with this floppy and then select CDROM installation. Does this help?
I have tried that with no luck. I have completed my installation with the hard
drive images and the system works well. I am not able to use the cdrom with the
Linux system either. I assume that the driver is the same in both instances. My
Linux 2.0.25 kernel works well with the cdrom. I thought I would later rebuild
the kernel and substitute in the old driver(s) and see if I have any luck.
There is probably not more that you can do to help me on this, it is either a
fluke in my system or just my bad luck. I assume it works well for everybody
Brent - would the nodma help here?
email@example.com, can you try booting the installer with 'linux ide=nodma'
and see if that helps?
I tried the command 'linux ide=nodma' and the result is the same as if I just
hit <enter> with no command. The systems messages on console 4 are identical.
I have recompiled the kernel, using K6 architecture and the problem with the
cdrom has disappeared and some multiple resets of the IDE during boot have also
disappeared. The system seems to be working normally in that respect now. I can
mount and read the cdrom. The original dump that opened this bug report is
probably connected to the IDE problem. I suspect that there is some glitch in
my cpu that makes it not quite up to an Intel cpu. I suggest that this be
