Description Tony Kocurko 2000-10-13 14:38:27 UTC
Hello,

After having gotten through the installation up to the point when the disk
is to be formatted, we get this pop-up window:

  Formatting / filesystem...

Soon afterwards, the system crashes with the following text, shown between
the lines of "===="s, displayed on the screen. Details of our configuration
follow this text. (I have included some typical "\" continuation formatting
in order to avoid ugly line wrapping.) The problem appears to have occured
in the mke2fs process, but you'll see that in the text below.

===========================================================================


Our configuration is a bit exotic in one respect only: We have two Promise
Ultra100 PCI cards installed. Otherwise, the system is fairly generic:

 1. CPU         = 733 MHz Pentium III 133 FSB FC-PGA
 2. Motherboard = Asus CUSL2
 3. Memory      = 512 MB
 4. Hard Drive  = Western Digital Caviar 14300 EIDE jumpered as master
                  on motherboard primary IDE port
 5. CD          = Hewlett-Packard CD-Writer Plus 8100i jumpered as slave
                  on motherboard primary IDE port
 6. Floppy      = none
 7. Graphics    = On-board Intel 815e VGA graphics connector
 8. Monitor     = AST SVGA-LR
 9. Hard Drives = 2 Promise Technology Ultra100 ATA/100 cards with a total
                  of 3 Maxtor Diamond Max80 80 GB drives on each, two on
                  one channel, and one on the other. Note, though, that
                  only the motherboard sees these six drives, since their
                  drivers are not loaded by the Linux "install" kernel.
10. NIC         = 3Com905TN, but we're not yet connected to the net.

Any ideas?

Cheers,

This is typically an indication of bad hardware, but as always its never
definitively that. I suspect its a memory/cpu issue. I've reassigned it to
kernel as if its not hardware thats where the problem will lie.

Please delete this bug, or mark it as resolved.

The problem seems to be caused by my having had the CD drive as slave to the
hard drive master on a single IDE port. Once, I moved the CD to the master
role on the secondary IDE port, leaving the hard drive as master on the
primary IDE port, the problem went away.

There is a new problem, however, which I will investigate further before
submitting a report.
