>Description:
	When my system is under heavy io load the system crashes with
Fatal trap 1: privileged instruction fault while in kernel mode
instruction pointer     = 0x8:0xc056f18d
stack pointer           = 0x10:0xe8e9baec
frame pointer           = 0x10:0xe8e9baf8
code segment            = base 0x0, limit 0xfffff, type 0x1b
                        = DPL 0, pres 1, def32 1, gran 1
processor eflags        = interrupt enabled, resume, IOPL = 0
current process         = 694 (bonnie++)
trap number             = 1
panic: privileged instruction fault

I have a core file but without debugging information. I Try to 
provide a kernel and core file with debugging enabled.  

>How-To-Repeat:
	Do some heavy IO (like mastering a Video DVD) 
>Fix:
	n/k
