[Hardware] ohci1394 oops (2.6.18-ovz-smp-alt22)

[Michael Shigorin]

	Здравствуйте.
Пока попалось, фиксирую:

# dmesg | /usr/sbin/ksymoops 
ksymoops 2.4.11 on i686 2.6.18-ovz-smp-alt22.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.6.18-ovz-smp-alt22/ (default)
     -m /boot/System.map-2.6.18-ovz-smp-alt22 (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.

Error (regular_file): read_ksyms stat /proc/ksyms failed
/usr/sbin/ksymoops: No such file or directory
No modules in ksyms, skipping objects
No ksyms, skipping lsmod

В dmesg дословно так:

Вообще говоря, у меня был один непонятный прецедент, возможно, 
с памятью -- с тех пор продувал, но зуб за неё не дам.
