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..?)
