Problem in Kernel Debugger Mode


Hello All,

i have some problem in my Linux Machine(2.4.17),it seems the application process is become looping.
So i could not able to access my system.So i have tried through kdb mode.Then i have dump the memory to dedicated
Crashdump partition.My system having Crashdump Mechanism.

The problem in when i have dump the memory,all system registers (eax,ebx,........,esp,eip) values like invalid values.
The values all are less than 0xc0000000(PAGE_OFFSET).All values are like user-space values.So my crashdump
mechanism could not able to dump memory.Because the computation of current process descriptor (esp & 0xffffe000) address
becomes invalid.

Could you please explain me,in this case how can i dump the corresponding kernel-space values (all pt_regs values)
in kdb mode.Then only i can able to dump the memory properly.After that only i can able to start my Crash analysis.


How to find the pt_regs address for this case,in kernel-space land.


Thankx & Regards,
Murali.S
