hi,
	I am incorporating MPLS (Multi Protocol Label Switching) support
to the linux kernel 2.4.9.

	I am getting oops when calling dst_alloc(). My oops file is 
enclosed with this mail.

Processor: Pentium III (coppermine)
RAM : 128 MB
OS: Redhat 7.0

Kernel Version: 2.4.9

Thank you in advance
kishore

ksymoops 2.4.0 on i686 2.4.9.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.9/ (default)
     -m /home/pg00/kishore/linux2.4.9/System.map (specified)

No modules in ksyms, skipping objects
Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid lsmod file?
Warning (compare_maps): mismatch on symbol partition_name  , ksyms_base says c0213090, System.map says c0150cf0.  Ignoring ksyms_base entry
  Receiver lock-up bug exists -- enabling work-around.

Overnight I had a couple of oopsen on my Athlon box, now I've had some
more when running rpm and ksymoops.

System is RedHat 7.1, Athlon 800, Abit KA7-100 m/b.

The 5th August CVS snapshot of the ieee1394 code had been applied (and
worked without incident for a month or so).

First, the one just now, when running rpm:

     -m /boot/System.map-2.4.9 (specified)
