Subject2.4.17 oops, again ("kernel BUG at page_alloc.c:76!")
I got this oops yesterday, on a 2.4.17 kernel on a k7 750 with 384mb ram and 
160mb swap. It took down XFree but I could still run programs on the VT, so I
attach the output of 'dmesg | ksymoops', 'free', 'lspci' and 'lsmod'. If
anyone's interested, I can mail the .config file as well.

I've had a lot of oopses on 2.4.17 lately; see for example
http://www.uwsg.iu.edu/hypermail/linux/kernel/0201.1/1628.html.

The kernel is tainted because of the nvidia NVdriver module v2313.
(but even without it loaded I recall getting oopses).

I tried running MemTest86 for about 35 minutes with no errors reported.

By the way, during bootup, i get a "spurious 8259A interrupt: IRQ7."
kernel message. Sometimes after all services have been started, other times just
before the initscripts are finished starting everything. It doesn't seem to have
any effect.. my printer seems to work fine (if lpt1 is related to IRQ7..?)

ksymoops 2.4.3 on i686 2.4.17. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.17/ (default)
-m /boot/System.map-2.4.17 (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.
