I'm attempting to get the ecc.o module loaded such that I can have the /proc/ram file reporting on my ECC memory single and multibit errors (rather than just trusting that everything is okay).

Here's the specifics:

RHELv3.0
2.4.21-9.ELsmp
motherboard: Supermicro X5DP8-G2
bios settings set to enable ECC
memory: 4 512MB DDR ECC DIMMs

Here's the output:

# insmod ecc
Using /lib/modules/2.4.21-9.ELsmp/kernel/drivers/char/ecc.o
/lib/modules/2.4.21-9.ELsmp/kernel/drivers/char/ecc.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg

I've also tried the --force option, same results. If I look at the tail of syslog, I see:

kernel: ECC: monitor version 0.14 (Oct 10 2001)
kernel: ECC: Unknown device 8086:254c.
kernel: ECC: Can't find host bridge.

(or with -force option)

kernel ECC: monitor version 0.14 (Oct 10 2001)
kernel ECC: Unknown device 8086:254c.
kernel ECC: Can't find host bridge.

lspci -v shows the following for the Host bridge memory controller:

00:00.0 Host bridge: Intel Corp. E7501 Memory Controller Hub (rev 01)
Subsystem: Super Micro Computer Inc: Unknown device 3480
Flags: bus master, fast devsel, latency 0
Capabilities: [40] #09 [1105]


Thanks in advance for any suggestions.
