Package: kernel-image-2.4.27-2-686-smp
Version: 22.4.27-10sarge1
Severity: important
Hello,
after somedays of uptime on our fileserver (nfs,samba) we get an
kerneloops (see below). This happens when running a chmod on large
filesystems (from cron).
We had similar problems with previous kernels 2.4.2[4567]--686-smp, too.
(e.g. bug #283115)
thank you
Stefan
-------------------------------------------
ksymoops 2.4.9 on i686 2.4.27-2-686-smp. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.27-2-686-smp/ (default)
-m /boot/System.map-2.4.27-2-686-smp (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.
