Cox <beau@xxxxxxxxxxx> [1.] One line summary of the problem: Patch that fixes my problem: Starting with 2.4.23-pre4 my system hangs during startup and/or is generally unstable (see patch in [ X. ] below.) [2.] Full description of the problem/report: Origionally I had catagorized this problem with the startup sequence; the system always seemed to hang when squid was started before mysql, etc. Moving squid near the end of the startup process, I thought the problem was in hand. However, the system (pre9) proved unstable (would not stay up for longer than one day.) The problem exibits itself with a solid 'hang'; no oops, no dumps, nada. [ 3. ] - [ 7. ] See previous posting; no hardware or configuration changes. [X.] Other notes, patches, fixes, workarounds: This patch to net/ipv4/netfilter/ip_nat_core.c fixed my problem in all 2.4.23 versions pre4 - pre9: --- linux-2.4.23-pre4/net/ipv4/netfilter/ip_nat_core.c 2003-11-08 03:01:59.000000000 -1000 +++ linux-2.4.23-pre3/net/ipv4/netfilter/ip_nat_core.c 2003-11-08 03:00:47.000000000 -1000 @@ -157,8 +157,8 @@ continue; } - if (!(mr->range[i].flags & IP_NAT_RANGE_PROTO_SPECIFIED) - || proto->in_range(&newtuple, IP_NAT_MANIP_SRC, + if ((mr->range[i].flags & IP_NAT_RANGE_PROTO_SPECIFIED) + && proto->in_range(&newtuple, IP_NAT_MANIP_SRC, &mr->range[i].min, &mr->range[i].max)) return 1; } It is simply a rollback of changes to ip_nat_core.c made in pre4.
