Description of problem:
Upgrading from RH 7.1 to 7.3 on SIS730S based motherboard. Get following kernel
EXT2-fs: unable to read superblock
cramfs: wrong magic
FAT: unable to read boot sector
isofs_read_super: bread failed, dev=09:00,
Kernel panic: VFS: Unable to mount root fs
Problem occurs when attempting to install from either cdrom or floppy. Others
have experienced identical error so it isn't particular to my hardware. Have a
SIS630 machine that rocks no problem and much of the peripheral glue (IDE
controller etc.) are essentially identical between the two chipsets.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Start installation on SIS730 based system (e.g. PCCHIPS M810LMR)
Actual Results: Get the aformentioned kernel panic.
Expected Results: Installation should have proceeded.
Let me know if I can help. I have the hardware local (RTP) access would help.
This panic occurs booting into the installer and before you get to the first
Yes. If I use the default graphical installer the machine hangs with a blank
screen. If I use the text based installer, I can see the panic. So I assume
that the panic is also happening with the graohical installer but the display in
in a state that prevents me from seeing the printk output.
Reassigning to kernel.
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases,
and if you believe this bug is interesting to them, please report the problem in
