>Release: 2.1.7 Release from CD-ROM
>Environment:
Unknown -- It is the base install of 2.1.7 from CD-ROM using
a boot floppy created with dd from the CD-ROM as described in
the install instructions.
>Description:
During install, while untarring the gnu sources, the system panics.
Sometimes it reboots without the panic. Orignally I had 24MB of
DRAM, thought it might be a bounce-buffer problem (I have an Adaptec
SCSI controller). Reduced to 16MB, problem still there.
Also saw corruption on other installs while trying to untar bin.
It said "error line 0: P" or something along
those lines. The last install output before the trap message
was: gnu/libexec/uucp/cu -- however, changing what I select to install
causes this problem at different points in the installation.
>From VTY2 during install, the message is:
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x0
fault code = supervisor read, page not present
instruction pointer = 0x8:0xf01218e5
code segment = base 0x0, linit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resme, IOPL = 0
current process = 68 (cpio)
interrupt mask = <NOTHING PRINTED>
My hardware:
Adaptec 1542CF SCSI Controller - also being used as floppy controller
Toshiba 2X SCSI CD-ROM
Novell Ethernet card (NE2000 compatible, Nat. Semi chipset)
ATI VGA card
Floppy Drive
Intel DX4/100 CPU / VESA motherboard AMI Bios
VESA Super I/O card for IDE, serial, etc.
2 IDE hard drives
External cache disabled, internal cache enabled
Previously I was running 2.0.5 with no major problems.
Devices configured during install:
154x Adaptec
Floppy controller
IDE controller IRQ 14
Both serial, lpt0 standard settings (disabled lpt1)
sc0 console
I disabled all non-existant devices and the NE2000
I labelled the serverity critical instead of high because I am unable
to install the distribution.
>How-To-Repeat:
It happens consistently during install process. I would be willing
to ftp an instrumented kernel and report the results if it will help.
I am booting from a BSD floppy to install. Feel free to contact
me for more information or if you would like me to try something.
