>Description:
When I run /stand/sysinstall I get a kernel panic. I wrote down the
error message (had to buy a pen for that ;) ). Here is comes:
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x24
fault code = superior read, page not present
instruction pointer = 0x8:0xc0202f70
stack pointer = 0x10:0xccec1c8c
frame pointer = 0x10:0xccec1c98
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 199 (sysinstall)
interrupt mask = none
trap number = 12
panic: page fault
This happens almost immediately when I run /stand/sysinstall, during
the first phase, where it says something like "Detecting devices (this
may take a while)". I started getting this problem after I enabled USB
in my kernel and attached a USB keyboard and mouse (Logitech Cordless
Desktop Pro).
I just modified my kernel to save crash dumps to the swap, and these
should be moved to /var/crash at startup. If you like I can generate
such a crash dump?
>How-To-Repeat:
If I restart the system, login as root and execute /stand/sysinstall,
I get the very same crash.
>Fix:
I really don't know any, I guess removing USB from my kernel config
would help. But then again, it *may* be something else.
