Subject: PROBLEM: __free_pages_ok() OOPS
Date: 04 Apr 2002 00:42:41 +0200 [thread overview]
Message-ID: <1017873762.14879.33.camel@bandit> (raw)
Hi,
This is my first post in this mailing list.
I'm using Redhat 7.2 distribution, with kernel v2.4.18. The only foreign
module is NVDriver. Here is how the oops looks like:
invalid operand: 0000
CPU: 0
EIP: 0010:[<c0129f1a>] Tainted: P

Here is the output of ksymoops:

----------------------------
As I see, it's located in the funcion __free_pages_ok, which is located
in /usr/src/linux/mm/alloc_pages.c. The oops is caused by a call to the
macro BUG(). Here is the source of the file:
[...]
if (page->buffers)
BUG();
if (page->mapping)
BUG(); <---- HERE
if (!VALID_PAGE(page))
BUG();
[...]
I think that's the BUG() that triggers the oops, correct me if i'm
wrong.
What I don't know is why page->mapping is nonzero. Does anyone here have
a clue on this.
Thanks for your time.
