[Asterisk-Dev] Aiee,killing interrupt handler

[Neha chhabra]

Hi!

We (a group of 4 computer engineering students,
including myself) have run 
into problems while trying to build a knowledge based
scheduler. Our project is due next month and we
desperately need your help.

We made a few changes in the linux kernel version
2.4.18-14.
We are trying to log the states of the processes per
clock tick resolution.For that we have made a few
changes in the timer.c function of the kernel. Here we
define a log structure and we add the pid and states
of all the processes to the log structure.
In the exit.c function we are printing the entries
from the log structure corresponding to that process
which is exiting. 

After recompiling the kernel we rebooted the kernel
with our new image but it gave the following error.

Kernel BUG at slab.c:1131!

Can someone please help us regarding this? Any and all
help or suggestions will be welcome.  We'll be deeply
indebted to you.  If you require any further
information on our troubles (or about our project in
general) I will provide it as soon as possible.

Thanking u in advance,
