Description of problem:
Fresh install of Fedora Core from Devel Tree (x86_64), boot image used
from 19.02.2004. Cannot get syslog service starting, fails and
segfaults. A bit difficult to find useful debug data as nothing is
[root@localhost root]# service syslog start
Starting system logger: [FAILED]
Starting kernel logger: [FAILED]
[root@localhost root]# syslogd -v
[root@localhost root]# klogd -v
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Start system...
2. Service won't start
Actual Results: Service unable to start, seg faulting,
Expected Results: syslog starting...

Running on SATA disks with software raid and lvm on top, sata_promise
selinux=0 in boot option (same error without this option, though)
Odd. What does an strace show?

Misc logs from strace
See attachments. Compared to a working system on same level (i386, though), the
strace log ends at the init of fstat64. There are more services segfaulting in
the same way - like httpd, smbd and crond. Some services like mysqld and sshd,
work fine though.
Lots of stuff seg faulting, so something form another component (kernel?)
Normally would be lots of stuff I could've messed up by playing around, but
this is a clean and fresh install on all new hardware.
Just a quick note, I ran memtest86+ to make sure my new hardware
wasn't faulty. No problems found.
Started playing around a little bit as there was released a more
recent kernel (kernel-2.6.3-1.96). However, this kernel did not
recognize my logical volume and failed at boot asking for e2fsck.ext3
and fixing (and so on). Booting with kernel-2.6.3-1.91 again brings up
the system, but with the errors mentioned in this bug report.
As I suspected the kernel to have problems, I found the previous
version , kernel-2.6.2-1.87, and was surprised to see everything work
with this version, lvm and everything. So for...

...the problems mentioned in this report are non-existent. For the
2.6.3 kernels I've tried (only from devel, not recompiled) the -91 seg
faults a lot, and -96 won't boot on my file system.
So I guess this bug should be moved away from sysklogd and the kernel?
I'm not sure how to do that, but I'm sure someone else knows. Thanks.
Problem with filesystem/lvm is not solved by upgrading kernels (-97,
-100, -106, -109, -110), but still works with -87 (2.6.2). With the
-91 kernel it also works for the filesystem, but all the seg faulting.
So cannot tell if it solves the actual problem.
I've noticed someone else logged a bug for the filesystem/lvm problem,
see bug number 116573, this is the exact same error - but not the one
the bug was originally logged for.
Yesterday I formatted and reinstalled the system from devel tree using
-106 kernel (25/2-2003), all same settings, and everything is just
fine. Also, after upgrades to -109 and -110 still works just fine.
So bug sort of solved I guess, closed it as "CURRENTRELEASE".
