>Description:
FreeBSD V3.3 system guttered for V4.0 installation. System previously
working, there were no changes or variations to the hardware.
Other slice uses Win95.
When using ifconfig to configure network, system crashes.
e.g. ifconfig le0 inet 10.0.0.1 netmask 255.255.255.0
This can be induced using standalone or muliuser mode. Crash screen details:
Fatal trap 12: page fault while in kernel mode
Fault virtual address: 0x0
Fault code: Supervisor read, page not present
Instruction pointer: 0x8:0x0
Stack pointer 0x10: 0xcccced7c
Frame pointer: 0x10: 0Xcccced90
Code segment = base 0x0, limit 0xfffff, type 0x1b
- DPL0, pres 1 def32 1, gran 1
Processor flag=interrupt enabled, resume, IOPL-0
Current process = 179 (ifconfig)
Inerrupt mask = net tty
Trap number = 12
Panic: page fault
---
Possibly relevant facts:
1. NIC Settings: irq 10, iomem 0xD0000, port 300
2. The NIC requires eprom settings, buffer size is 64K, which its been since 2.2.5
3. Unfamiliar kernel messages during boot:
le: drier is using old-style compatability shims
le0 XXX: driver didn't set ifq_maxlen
4. A crash also results when installing fresh from CD and configuring the network.
5. These problems were also experienced from the ISO image via a web copy.
(Though I suspected a fouled CD burner.)
6. System is a Pentium III with 256Mb memory.
>How-To-Repeat:
Install fresh system, do not configure network interface
Boot system
Login to root account
ifconfig le0 inet 10.0.0.1 netmask 255.255.255.0
