SubjectRe: Oops in 2.2.19
The previous ksymoops was from 2.2.21.  The ksymoops from 2.2.19 follows, 
which looks somewhat similar.

Sorry for the confusion.

Aaron.

ksymoops 2.3.4 on i686 2.2.19-cpproxy-1.0.0. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.2.19-cpproxy-1.0.0/ (default)
-m /boot/System.map-2.2.19-cpproxy-1.0.0 (specified)

Warning (compare_maps): ksyms_base symbol module_list_R__ver_module_list
not found in System.map. Ignoring ksyms_base entry
