Well, I was writing a form in Opera browser(6.0TP1, a beta release), in the
spanish clone of slashdot.org (barrapunto.org)
when suddenly the window dissapeared, and when i looked into syslog, it
said
this:

I don't know if this is because due to Opera, or it's the kernel itself. So
if this mail should not be in this mailing list, please ignore.
(I'm running 2.4.17-pre2 in a cyrix 6x86MX 200Mhz 32MB machine, motherboard
is a MSI-5146 with a SiS 5571 Trinity chipset, gcc version 2.95.4)
This is the second time I send this message, but i've not seen it in the
list.....so please forgive me if you see it twice

> Could you run this Oops through ksymoops and send the output?
ksymoops 2.4.3 on i686 2.4.17-pre2. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.17-pre2/ (default)
-m /boot/System.map-2.4.17-pre2 (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.
