SubjectPROBLEM: 2.4.23-pre7,pre8,pre9 hang on starting squid
Date
[1.] summary:

2.4.23-pre7,pre8,pre9 hang depending on when 'squid' is started.

[2.] Full description:

Running up-to-date Sorcerer.

One machine hangs consistently when this sequence of daemons
is started in runlevel 3:

S26networking ifconfig etho, eth1, eth1:1 & routes
S28firewall firewall viaiptables
S30portmap 5beta
S32ntpd 4.2.0
S34named bind 9.2.3
S36nfs
S38rpc.bootparamd
S40xinetd
S42squid 2.5.STABLE4
S44mysql 4.0.15a
S46xmail xmailserver mail server 1.17
S48spamd
S50apachectl 2.0.48

It works flawlessly when squid is put to the bottom:

S26networking
S28firewall
S30portmap
S32ntpd
S34named
S36nfs
S38rpc.bootparamd
S40xinetd
S42mysql
S44xmail
S46spamd
S48apachectl
S50squid

Why am I bothering you kernel folks with what looks like a pure
SA problem?

1. This machine works flawlessly (with squid started before
mysql, etc.) unter 2.4.22.
2. Four other machines running the same software (I compile
my own packages via Sorcerer) using 2.4.23-pre9 and squid
above.
3. This problem is solid on this one machine. Always reproduceable.
Always hangs with squid. No dumps found. Just HANG.

[3.] Keywords (i.e., modules, networking, kernel):

2.4.23-prex squid

[4.] Kernel version (from /proc/version):

Linux version 2.4.23-pre9 (Beau E. Cox: beau@beaucox.com) (gcc version 3.2.3)

[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)

-none-

[6.] A small shell script or example program which triggers the
problem (if possible)

-n/a-

[7.] Environment
[7.1.] Software (add the output of the ver_linux script here)

Software enumerated above.

[X.] Other notes, patches, fixes, workarounds:

I have everthing working now, so this ?bug? is not bothering me.
I may well be something sloppy I have done on my end, having nothing
to do with the kernel, but the kernel is the only thing changed(???)
