1. amd/nfs can not mount other disks under 2.4.3 BigMem kernel
2. I compiled 2 kernels(one with BigMem, one without).
Both are SMP kernels.
The one without BigMem supports works just fine.
The only difference is that I turned on BigMem support, and recompiled kernel and
modules.
When I try to mount other disks through amd, it says: "No such file or directory."
The log file for amd(/var/log/amd) after initial startup info says:
----

/etc/amd.fsmap on /fs fstype toplvl

When I try to restart amd, the log file (/var/log/messages)
has the following lines associated with amd startup
----

Noting that the insmod nfs failure may be responsible, I try to "insmod nfs" as
root as follows:
