I do not know about your current problem, but I installed a dual server at a clients site only to find a white paper which discussed the un-stability of SAMBA on a dual intel server.  I experenced all the possible problems you could imagine.  They only cleared up when I replaced the dual system with a P4 single cpu system,  Loaded from the same CD.  If you do not need SAMBA/Windows networking then keep trying to fix your system.  If you do, then I recommend setting up a single CPU system.  My experience had my users being kicked off the network twice a week.  Very bad.

Really? Do you have a URL for the paper you mention? I'd be interested in having a look. It would be quite unusual for an application to be affected by the number of processes, since only the kernel concerns itself with multiple processors.

Well Laurent, I have had major problems with regards to updating my SME 5.5 servers with update2 also. The problems that I was having though seemed to only happen when I had changed the hardware from its original installing hardware. I would get errors missing swap or it just would'nt load LILO or could'nt find the / directory.

This may not have any relevance to your situation, you may just need to recreate the swap file.

Bonjour et Merci,

More indication for my problem :

1. PC installed with 5.1.2 dual cpu work
2. Upgrade 5.5 dual cpu work
3. Upgrade update2 dual cpu dont work and problem (Enabling swap........)
4. Reboot on single cpu (e-smith up) pc work

So i dont have problem with lilo or samba or more but i believe that up2 make a change and i am affected only with dual cpu

Laurent,

For what it's worth, I have a dual CPU server, running SME 5.5 with update 2 installed.  It was a fresh install of 5.5, I loaded the first update as it was immediately availble after the initial install, then I loaded update 2 when it was released.

It's a generic box, a Tyan MB, dual PII - 233's, I'm using an old Proliant 2/P raid card and 3 huge 20GIG drives in RAID5 array, 384meg RAM. (incase you're interested in taking a look: http://www.dgwebhosting.com/sysinfo).

PPro's aren't supposed to be plagued by needing the same stepping codes (PII & P3's MUST be same step code, +/- 1), but I have heard there are certain instances where this may be a problem, don't recall the specifics though, it's supposed to be up to the system's BIOS.  

Have you tried flashing to the latest BIOS version on your MB?  Just a guess.

Has anybody got SME 5.5 working with Dual AMD CPUs on a Tyan 2466-4M?

It seems to fall down when it gets to the IDE section on start up. There is no problems installing though.

I have given up on it ATM, but it would be very nice to get a fix for it.

BTW, SME 5.6 beta 7 doesn't like it either.
This would be a big selling motherboard to suit dual AMD CPUs, I'm very surprised and disappointed E-Smith won't work on it.

I've read that dual AMD's aren't supported under SME 5.5, a kernel version issue.  It's supposed to be supported under 5.6.  SME 5.5 is Linux kernel 2.2.something and 5.6 is kernel 2.4.something.

As for the install dying at the HDD initialization, I've also read that some drives (WD?) report capabilities that aren't fully supported.  When SME attempts to use those capabilities and the drives can't respond properly, SME will die.

I'd say to search here for topics related to IDE or install failures for more details.
