Hi,

i've just discovered this oops in my logs. it's a plain red hat
linux 7 system with all updates applied (incl. glibc 2.2). the
kernel running is a stock 2.4.0-test9.

i have no idea what could have caused this oops but i'm running an
onstream di-30 tape streamer with the ide-tape.c driver. could that
be it...?!

Thilo

PS: this is my first posting so please bear with me... ;-)

-------------------------------------------------------------------
ksymoops 2.3.4 on i586 2.4.0-test9. Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.0-test9/ (default)
     -m /usr/src/linux/System.map (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.
