FreeBSD学习

今天早上到公司以后,习惯性的SVN,突然发现SVN服务器连接不上,打开服务器的显示器,发现了下面的代码:

[code]
kernel trap 12 with interrupts disabled

Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0x48
fault code = supervisor read, page not present
instruction pointer = 0x20:0xc0686e83
stack pointer = 0x28:0xe5738ce4
frame pointer = 0x28:0xe5738d00
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = resume, IOPL = 0
current process = 45 (schedcpu)
trap number = 12
panic: page fault
cupid = 0
Uptime: 1m27s
Cannot dump. No dump device defined.
Automatic reboot in 15 seconds - press a key on the console to abort
Rebooting...
cup_reset: Stopping other CUPs
[/code]

这东西着实很让我郁闷,因为我根本不知道是怎么回事。在google了无数次+论坛求助以后,基本确定是硬件出问题了。后来根据论坛上的帮助,我将BIOS全部恢复成默认以后,就没有问题了~奇怪~

虽然最终还是没有弄明白这个是怎么回事,不过好歹没问题了。把报错信息保留下来,也许某一天我回来看的时候都全明白了。

另外,今天发现两个很有用的地址,一个是最新的FreeBSD6.2的handbook:

另外一个是关于port和package的安装QF:
