Giliberto >Organization: None >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 = My hardware: Adaptec 1542CF SCSI Controller - also being used as floppy controller Toshiba 2X SCSI CD-ROM Novell Ethernet card (NE2000 compatible, Nat.

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. >Fix: >Audit-Trail: >Unformatted:
