[2.3.43-pre6] swapon and pppd oops

Hi,

Kernel modules 2.3.6
Gnu C egcs-2.91.66
Binutils 2.9.5.0.16
Linux C Library 2.1.1
Dynamic linker ldd (GNU libc) 2.1.1
Procps 2.0.6
Mount 2.10
Net-tools 1.51
Console-tools 1999.03.02
Sh-utils 1.16

Swapon oops:

ksymoops 2.3.3 on i586 2.3.43. Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.3.43/ (default)
     -m /usr/src/linux/System.map (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.

No modules in ksyms, skipping objects
Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid lsmod file?
