Description Xander D Harkness 2002-05-24 10:59:16 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.0+) Gecko/20020519

Description of problem:
Red Hat will not install on my laptop (even though Debian will.)
Red Hat versions 7.1, 7.2, 7.92 and 7.3 all fail at the same point with the
following message:
EXT2-fs: unable to read super block
cramfs: wrong magic
FAT: unable to read boot sector
isofs_read_super: bread failed, dev=09:02, iso_blknum=16, block=32
Kernel panic: VFS: Unable to mount root fs on 09:02

At which point it stops.  I have formatted the whole filesystem, installed
Debian on it twice.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Put in Red Hat boot media (floppy or CD)
3.Error above obtained.  Will only hard reboot

Actual Results:  System hangs

Expected Results:  Red Hat installation

Can you give some description of the hardware ? CPU, ram, videochipset etc ?
Comment 2 Xander D Harkness 2002-06-12 08:20:59 EDT
celeron 733
128Mb ram (16 shared with video)
SiS 630 video
6 Gb Hard drive

Please note that I have had Red Hat previously installed on this machine.

After the reported error I have done a full format of the drive and run scan
disk and had no reported errors.

Sorry for the delay

I've had a report where the "shared" bits somehow got misdetected.
Could you try passing the mem=111M parameter to the kernel and see if that helps?

Yipppeeee, yes it does, I have a functional laptop again.

Thanks very much.

Kind regards
Comment 5 Arjan van de Ven 2002-06-18 04:01:00 EDT
Could you attach the dmesg output from a normal boot?
Maybe I can see something that indicates what's up (or maybe there's nothing
special.. who knows)
Comment 6 Xander D Harkness 2002-07-25 04:50:25 EDT
That worked very well indeed.

Thanks very much :-)
