Description of problem:
On my 64-bit system, running FC5 test1, I get a wild variety of IP addresses for logins, per last -i output. Does not happen on my 32-bit system running FC5 test1, or my Ubuntu breezy system, both on the same network.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
2.Also appears when I run utmpdump /var/log/wtmp
Actual Results: Lots of strange IP addresses, including from impossible locations, e.g. from external networks during the boot and shutdown process. If I were being hacked, I'd think I'd get a similar result on my 32-bit system running FC5 test1.
Expected Results: IP address output from last -i should be 0.0.0.0 unless I log in from another system.
When I run last -i, I get entries like:

michael pts/1 18.104.22.168 Fri Dec 16 12:41 - down (13:26)

Seems reminiscient of bug 82540, but I don't see this problem on my other FC5 test1 system running on a 32-bit laptop.
These bugs are being closed since a large number of updates have been released
after the FC5 test1 and test2 releases. Kindly update your system by running yum
update as root user or try out the third and final test version of FC5 being
released in a short while and verify if the bugs are still present on the system
.Reopen or file new bug reports as appropriate after confirming the presence of
this issue. Thanks
This isn't actually a last bug; programs are putting junk in the file due to a
reboot/init is one of them; this is fixed in SysVinit-2.86-9 or later.
Assigning to util-linux for the other part of the fix.
Thanks. Fixed in util-linux-2.13-0.37 or later.
