The lx50 has incompatible bios acpi tables, so the 'acpi=off' kernel
parameter must be used. Also tried using the 'noapic' parameter
without effect.

label lr4a4
  kernel r4a4/images/pxeboot/vmlinuz
  append acpi=off ksdevice=eth0 console=ttyS1,9600n8 load_ramdisk=1
network ks=nfs:

Using different nfs servers (rhas21, r4a4) resulted in hangs at
slightly different places.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. pxe boot nfs install from rhas21 server (see syslinux target above)
2. nfs retries begin to occur loading rpms such as glibc

Actual Results:  installation hangs.

Expected Results:  installation completes.

Additional info:

I'll attach a tcpdump and lspci.

Comment 4 Christopher P Johnson 2004-08-17 20:33:11 EDT
This appears to be related to the bmc and ipmi setup. Disabling
the ipmi lan configuration allows the installation to complete.

Apparently there are specifics with adapter setup that are required
for the bmc and e100 to work together.

The lan setup is unexceptional:

ipaddr: 10.6..73.75

Not finding reports on the scb2 motherboard. Earlier motherboards:

Comment 5 Christopher P Johnson 2004-08-20 13:39:09 EDT
intel.com indicates that this may be fixed in e100 version 3.0.27:

Subject: RE: intel scb2 server, e100 driver and ipmi interference on
From: adaptersuppor@mailbox.cps.intel.com

Version 3.0.18 was a development version. The first stable version of
the 3.0.x driver was 3.0.27. Can you try that one? If the issue
persists with 3.0.27, please confirm that the issue does not happen
with 2.3.43.

Comment 6 Jason Baron 2004-10-15 17:36:14 EDT
rhel4 B2 includes the 3.0.27 e100, we will re-test there.
Comment 7 Christopher P Johnson 2004-11-05 16:35:16 EST
This bug is happening with the r3u4 beta as well.

The workaround is to install with another protocol (ftp succeeded).
As I recall, there have been previous problems with the bmc swallowing
nfs packets, thinking they are ipmi.
