I've seen this happen before, back when something was haywire with my
client's NIC; it was one of those gradual failures. Swapping NIC's did
the trick then. I've also (rarely) seen an NFS misconfig do it; this
is rare because it's autoconfig'd during the K12LTSP setup. I'm
assuming here that you've left /etc/dhcpd.conf (or
/etc/dhcpd-k12ltsp.conf) at its stock config.|
Can you try this: boot a thick client Linux box, try mounting /opt/ltsp/i386 from the LTSP server, and copying everything under there to a test directory on the thick client?
Also, do you have another kind of thin client to try out to see if it happens there, too?
Do you GNU?

Rob, thanks a lot for the suggestion. I have tried gPXE, but with the same result. The problem arises AFTER Linux kernel is downloaded from the server and started. The kernel says: ...

Subject: Re: [K12OSN] Network boot hangs I had a similar problem and found that some clients would not boot with an etherboot cd, but they would boot with a gPXE cd. Try that. You can get it from www.rom-o-matic.net. When it comes to the driver selection part, choose gpxe from the drop-down list. -Rob On Mon, Feb 09, 2009 at 10:54:44AM +0300, Peter Trifonov wrote:Hello, I have installed K12LTSP 5-EL/32 bit onto a server in my network.
