Can you switch ttys when the hang occurs? 

I'm not shure if I can switch in all cases. But in the moment I had a
hung during formatting, and I can switch ttys. (and I can execute commands
in the alt-f2 window). 
In alt-f5 it is in the state 'writing superblocks and filesyste accounting 
information:'

Previous I had a hung during the package installations. And when I switche
to alt-f2 and type ls, there was no repsonse anymore. But before this
I looked at the other windows and found the following error messages:

alt-f5:
/usr/sbin/hwclock: error wile loading shared libraries: libaudt.so.0: cannot 
open shared object file: No such file o
r directory
alt-f4:
audit(...): avc: denied ( transition) for pid=738 comm="anaconda" 
name="libgcc_post_upgrade"
  dev=dm-0 ino=524293 scontext=system_u:system_r:anaconda_t:s0 
tcontext=system_u:syste_r:rpm_script_t:s0 tclass=proc
ess

this is a little involved, but hopefully it'll yield something interesting..

when its hung, go to tty2, and run these commands

echo 1 > /proc/sys/kernel/sysrq
echo t > /proc/sysrq-trigger
*put a blank floppy into the drive*
modprobe floppy
dmesg -s 128000 > /dev/fd0
sync

then read back what was written on another box with strings /dev/fd0 and attach
output to this bug.

Traceback of hung during formatting

This traceback/dmesg is from the case where the process stops during 
formatting auf filesystems (note that I did a lot auf looking arround
int ALT-F2 before creating the traceback). Between the hung and the
actual traceback was more than 24 hours. The messages in ALT-F3/4/5 described
in a previous comment belong to this situation !

I now reproduced the situation where the hung occurs during 'Package 
Installation' of glibc-2.3.90-37-x86_64, Size 10957k, Status: 92%,
Total Packages 291, Completed 9, Remaining 282, 15%.

When I type in 
   echo 1 > /proc/sys/kernel/sysrq
in ALT-F2, I don't get any prompt. So I cannot do make the traceback.

The last lines in ALT-F3 were:
INFO: moving (1) to step preinstallconfig
WARNING: no dev package, going to bind mount /dev
INFO: moving (1) to step installpackages
INFO: Preparing to install packages

The last Lines in ALT-F4 were:
SELinux: initialized (dev dm-1, type ext3), uses xattr
audit(1141685663.010:3): avc: denied (transition) for pid=739 comm="anaconda"

scontext=system_u:system_r:anaconda_t:s0
tcontext=system_u:system_r:rpm_script_t:s0 tclass=process

the last line in ALT-F5 was:
/usr/sbin/hwclock: error while loading shared libraries: libaudit.so.0:
 cannot open shared object file: No such file or directory

this sounds similar to my bug 185395 .. i assume your server has a smartarray
card for the disks?

i think the problem is in the kernel (my system runs okay using the FC4 kernel
following a yum upgrade from FC4) .. is there a way of running the FC5 PXE
install using the vmlinux and initrd from the FC4 install - or rebuilding those
files using the FC4 kernel?

i think bug 185395 is fixed by kernel 2.6.15-1.2054_FC5smp in the FC5 release so
it might be worth trying this again now.

FC5 Release works fine now.
