Hi,
I have got this two Oops with 2.2.15pre14. (I can obtain
similar Oops with 2.2.15pre[9-14]. It also fails for 2.3.51.
I am running an application with a lot of small mmaps in a big file
(~400MB), and I do a lot of msyncs in small parts of the file. (This
causes other application to be killed or like here, get kernel Oops).
I can give more information on request, test patches, and appreciate
comments and also fixes :-)
If you need something else let me know.
Thanks in advance, Juan.
My configuration is:
