Hi everyone,
I apologize for sending this to both the Linux kernel mailing list as
well as the Linux-XFS mailing list. I am sending this to the lkml
because it's a kernel bug report. I'm sending this to the Linux-XFS
mailing list because I do not know if "try_to_free_buffers+130/240" in
the Call Trace has anything to do with changes that the XFS team has
done on the Linux kernel.
I got kernel BUG reports in my system logs[1] and dmesg[2] four times
today. The first time it happened with process kswapd, the second with
process httpd (of Apache), the third and fourth with ssh which I was
firing up through wterm. They happened all within a fairly short period
of time: the first at 16:02:05, the second at the same time, the third
at 16:03:51 and the fourth at 16:03:53.
I am running Linux kernel 2.4.19-rc2-xfs (CVS snapshot 20020718),
compiled using the current gcc-3.1 Debian packages from Sid (gcc version
3.1.1 20020703 (Debian prerelease) according to `gcc-3.1 -v`), on an AMD
Duron/850MHz. This system has been running continuously using this
kernel for 7 days 22:13, according to uptime. I didn't do anything
special this afternoon when all four kernel BUG incidences occured.
Would any of the kernel or XFS developers want me to do anything to
perhaps help debug this situation? I intend to move this system up to
2.4.19-rc3-xfs (CVS snapshot as of today), otherwise.
Thanks a lot in advance.
--> Jijo

Ah, yes, I had forgotten to do that. I hadn't realized that the same
requirement for reporting oopses held for reporting kernel BUGs. My
sincerest apologies. I ran all four through ksymoops at once, and it
worked so I guess this is a valid thing to do. I am still running the
same configuration and haven't even rebooted, so I did not have to
change any of ksymoops's defaults.
The 'decoded' message follows.
Thanks for the help.

[1] Kernel BUG reports from dmesg passed through ksymoops:
ksymoops 2.4.5 on i686 2.4.19-rc2-xfs. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.19-rc2-xfs/ (default)
-m /boot/System.map-2.4.19-rc2-xfs (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.

Let me guess: you're using nvidia's binary only module? if so please go
and complain to them, this oops is characteristic for their buggy driver.

I had further forgotten to mention that I have the NVidia 2960 binary
module loaded, and that D. Stimits just posted a message on the
Linux-XFS mailing list about a kernel BUG report also on page_alloc.c:91
on a similar 2.4.19-rc2-xfs CVS snapshot, also with the NVdriver module
loaded.
Kjell Randa noted that an upgrade to version 2960 fixed things for him,
and Kjell Randa added that removing "agpgart" support fixes things. I
have agpgart support for my VIA chipset, and it's possible that this is
clashing with the NVdriver.
I realize that I may have wasted people's time, since the NVidia driver
is closed-source binary-only, and my system is tainted. I apologize for
this but hope that my messages will at least help some other people who
may run into this problem and will search the archives.
I am upgrading to 2.4.19-rc3-xfs now, and will remove agpgart support
from the kernel. I am keeping my fingers crossed.
