Description dshapin 2001-07-11 13:04:44 EDT
From Bugzilla Helper:
User-Agent: Mozilla/4.7 [en] (Win95; U)

Description of problem:
Redhat 7.1 Anaconda does not load the install program on a Compaq Proliant 1500 with 128MB and an integrated
wide fast scsi-2/p controller. I can install Red Hat 5.2 on this computer from the CD, but the 7.1 install does not work.

How reproducible:

Steps to Reproduce:
2.Loads image files
3.Then Anacondo tried to start the install and an errorr occurs - not enough memory to install on Red Hat on this machine.

Actual Results:  The Install process aborts and the machine reboots.

Expected Results:  The install process to load and continue.

Additional info:

I opened a support call with Red Hat and they said there are known problems with 7.1 and scsi controllers.
Comment 1 Matt Wilson 2001-07-12 10:46:01 EDT
Boot the machine with:

"linux mem=exactmap mem=128M@0"
Comment 2 Arjan van de Ven 2001-07-12 10:55:21 EDT
"linux mem=exactmap mem=640k@0 mem=128M@1M"
Comment 3 dshapin 2001-07-12 14:28:28 EDT
The install process went further with the "linux mem=exactmap mem=128M0" however I got the error message

python: header.c:511 headerLoad: Assertion 'rdlen == dl' failed install exited abnormally -- recieved signal 6 sending termination

CTL-DEL-F3 screen last linees display

* Detected 128M of memory

It appears the swap space was not created properly on the drives.

Comment 4 dshapin 2001-07-12 16:17:00 EDT
Removed two of the three Compaq Hot pluggable 4.2 GB drives to see if maybe the drive array was causing a problem. 

When I booted with one hard drive it got as far as copying the image to the hard drive and then the kernal paniced.

Looks like it is unable to mount the root. SCSI controller problem? The scsi controlle works fine with Red Hat 5.2.
Comment 5 Arjan van de Ven 2001-07-12 16:18:17 EDT
that is with 
"linux mem=exactmap mem=640k@0 mem=127M@1M"

Comment 6 dshapin 2001-07-12 17:38:01 EDT
I booted with linux mem=exactmap mem=640k@0 mem=128M@1M

Thanks that worked!
Comment 7 Arjan van de Ven 2001-07-12 17:46:49 EDT
Ehm I made a typo, it needs to be "127" not "128", eg 1 less than you have,
so it is 640Kb in "low memory" and an additional 127Mb in "high" memory.

Also, if you install the updated 2.4.3-12 kernel, you can use the old style
"mem=128M" again.

Comment 8 Panic 2001-08-14 16:41:54 EDT
This workaround is confirmed to work with at least one other machine, this time
a ProLiant 1500 with a SmartArray 221 (4 drives, RAID5).
