Hi,

Most of yesterday I spent time installing SL.40.042005.i386 onto a couple of 
my rack systems. One of them uses a Hyperthreading CPU which I've used under 
HT mode without issues under SL3.

However SL40 (aka the vendors newer kernel) has major issues running in HT 
mode (UP mode works fine), and just has a hard lock-up during the boot 
process, where the only thing that can be done is to press the power off 
button.

I've tracked this down to a bugzilla filed for FC3:

https://bugzilla.redhat.com/bugzilla-old/show_bug.cgi?id=146921

where I get _exactly_ the same issue this guy reported. I disable the 
various services where the hard lock-up occurs, and it gets past them but 
then on the login prompt, after entering the username and password the 
prompt just sits there and you can't login.

After alot of trouble-shooting on this problem, I tracked it down to the 
ACPI support, once I put in:

acpi=off

into the kernel grub command line, the system booted and runs fine in HT 
mode. From that bugzilla report, it doesn't look like anything has been 
fixed with that bug yet.

On a side note, I also experienced that "kernel openafs anaconda" problem 
when burning those ISO's above and installing them onto my rack servers (the 
error reported by another guy earlier in this list). The way I got round 
that problem was to do a vanilla "server" install on selection menu (without 
specifying the packages I wanted and didn't want), and SL40 installed, I 
then went back into the packages and selected/deselected what I wanted.

Do I need to download the new ISO's (042505) and re-install these newly 
built machines with these ISO's? or is the ISO set I have fine?

Michael.
