Re: 2.4.21-pre3-ac4 oops in free_pages_ok

[Bryan Andersen]

I too have been seeing this oops crash problem.  I can
consistantly reproduce mine by running:

   $ mke2fs -c -j -i 16768 /dev/hdc6

The interesting thing is running:

   $ mke2fs -j -i 16768 /dev/hdc6

does not cause an oops crash.  The only difference being
the bad block scan.

These are the outputs of ksymoops for the stack trace part
of the oops output from.  Kernel version is
linux-2.4.21-pre3-ac4.

I'm going to do further tests with the generic IDE
driver instead of the NVIDIA one.  Then I plan on
teasing out the NVIDIA2 specific stuff from the ac4
patch and only applying them to a pre3 patched kernel.
