Hi all !

[1.] 2.4.20pre8aa2 failed assertions in ip_{conntrack,nat}_core.c

[2.] Full description of the problem/report:
I'm running 2.4.20pre8aa2 with all the firewalling stuff enabled 
on a Pentium 75 and get occasionally
----  snip (lines broken to keep it readable) ----
Oct 10 20:00:04 fw kernel: ASSERT ip_conntrack_core.c:97
                             &ip_conntrack_lock readlocked 
Oct 10 20:00:04 fw kernel: ASSERT ip_conntrack_core.c:1067
                             &ip_conntrack_lock not readlocked 
Oct 10 20:00:04 fw kernel: ASSERT: ip_nat_core.c:841
                             &ip_conntrack_lock not readlocked 
Oct 10 20:00:04 fw kernel: ASSERT ip_conntrack_core.c:97
                             &ip_conntrack_lock readlocked

                             &ip_conntrack_lock not readlocked 
----  snip  ----
Otherwise everything is working fine.

[3.] Keywords (i.e., modules, networking, kernel):
     networking, firewalling, connection-tracking

[4.] Kernel version (from /proc/version):
Linux version 2.4.20-pre8aa2 (...) (gcc version 2.95.4 20010319
(prerelease/franzo/20011204)) #2 Wed Oct 9 20:43:34 CEST 2002

[6.] A small shell script or example program which triggers the
     problem (if possible)
Simply http'ing or ftp'ing trigger it occasionally. The symptom is 
that a particular (TCP-)connection "freezes".

[7.5.] PCI information ('lspci -vvv' as root)
Omitted since it is far more than 80 chars wide and IMHO not 
interesting in this case. Can actually send it if someone wishes.

[7.6.] SCSI information (from /proc/scsi/scsi)
No SCSI hardware.

[7.7.] Other information that might be relevant to the problem
       (please look in /proc and include all information that you
       think to be relevant):
Actually don't know really in this case. Is there any interesting?
