1. How do you boot the kernel? Bootrom?
If yes: Which protocol? PXE + pxelinux? Etherboot? ...
Yes, pxe on the Intel card plus pxelinux. The machines are diskless
with Tyan S2466 motherboards. I don't use the on-board 3Com ether chip
(which works and boots fine, btw).
2. Does ip auto configuration (e.g. ip=dhcp at kernel command line) work?
If you do see the "IP-Config: Complete:" message while booting
Yes, this works fine. The kernel gets it from pxelinux directly via
option IPAPPEND.
Here's what I copied manually from the screen after the IP-Config:
line:

I said before that there is a progressive degradation at each kernel
version. Some versions before 2.6.12.2/driver 2.6.11 there were no
portmap problems at all. 2.6.12.2/driver 2.6.11 says that it couldn't
get the port number from the server but manages to boot using the
default.
4. Could it be that you try to mount root using nfs version 2?
The current linux nfs 2 server is unable to serve the current nfs 2
client.
Wonderful :-(
Unfortunately version 2 is the default. Add the v3 parameter:
root=/dev/nfs nfsroot=%s,rsize=8192,wsize=8192,v3
Why do the previous versions work? Why does 2.6.15.2 work with a
Marvell/Yukon ether chip?
Trond asked about using tcp. I prefer to use udp because it has less
overhead. This is a computing cluster, all machines are in the same
room connected to a HP 4108gl gigabit switch. It's not a cable or
switch port problem, all machines exhibit the same behavior.
