...fails on ARM with ESTALE (116):
Looking up port of RPC 100003/2 on 192.168.0.4
Looking up port of RPC 100005/2 on 192.168.0.4
nfs_get_root: getattr error = 116
nfs_read_super: get root inode failed
VFS: Unable to mount root fs via NFS, trying floppy.
It seems to be related to these two compiler warnings:
gcc -D__KERNEL__ -I/usr/src/v2.4/linux-ebsa110/include -Wall
-Wstrict-prototypes -O2 -fno-strict-aliasing -fno-common
-pipe -mapcs-32 -march=armv4 -mtune=strongarm110 -mshort-load-bytes
-msoft-float -c -o nfsroot.o nfsroot.c
nfsroot.c: In function `root_nfs_get_handle':
nfsroot.c:444: warning: passing arg 3 of `nfs3_mount' from incompatible pointer type
nfsroot.c:446: warning: passing arg 3 of `nfs_mount' from incompatible pointer type
The following patch changes every instance of nfs_fh in nfs_mount to
be nfs3_fh. This makes NFS root mounting again a possibility on ARM.
