Ksysmoops output. Means nothing to me tho ;(

ksymoops 2.4.4 on i686 2.4.20ctx-17. Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.20ctx-17/ (default)
     -m /boot/System.map-2.4.20ctx-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.

No modules in ksyms, skipping objects
Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid lsmod
file?

Will the ctx-17 patch apply to the 2.4.21 pre release though?

run it through ksymoops (on the crashing machine)

line 100 means that page->buffers isn't empty on _free_pages_ok ...

take a look at the changelogs, if I remember correctly
this is fixed in one of the 2.4.21 prereleases ...

best,
