Oops in iput

[Florian Lohoff <flo@rfc822.org>]

Hi,
oops in iput - Kernel 2.2.19/i386 + ide-udma patches + ext3 patches (0.0.7a)

Intel BX chipset, SCSI Disks Symbios chipset - The crashing process
is the master process of "postfix" an MTA.

Just before the crash all processes on that machine started to segfault
in nameserver resolution (remote dns server) and after 2-3 minutes
this oops happened.



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

     Why is it called "common sense" when nobody seems to have any?
