Hi!

Ниже выдача ksymoops.  Какую полезную информацию я могу извлечь?
Background: опакечиваю user-space поддержку Zyxel Prestige 630 EE (630-11)
Запускаемая ручками инициализация/прибитие работает без проблем.  При
попытке запустить то же из hotplug поймал oops:

akhavr@netmaster /tmp/amedyn/scripts $ sudo /usr/sbin/ksymoops < /var/log/messages
ksymoops 2.4.9 on i686 2.4.25-std-up-alt1.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.25-std-up-alt1/ (default)
     -m /boot/System.map-2.4.25-std-up-alt1 (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.

Warning (compare_ksyms_lsmod): module ext3 is in lsmod but not in ksyms, probably no symbols exported
