I just tried this on my Canyonlands with the kernel.org 2.6.26 release:
e1000e: Intel(R) PRO/1000 Network Driver - 0.3.3.3-k2
e1000e: Copyright (c) 1999-2008 Intel Corporation.
e1000e 0001:81:00.0: enabling device (0006 -> 0007)
eth0: (PCI Express:2.5GB/s:Width x1) 00:1b:21:04:a3:47
eth0: Intel(R) PRO/1000 Network Connection
eth0: MAC: 1, PHY: 4, PBA No: d50854-003
...
-bash-3.2# uname -a
Linux canyonlands 2.6.26 #2 Fri Jul 18 16:46:00 CEST 2008 ppc ppc ppc GNU/Linux
-bash-3.2# dd if=/dev/zero of=/mnt/test bs=512 count=2
2+0 records in
2+0 records out
1024 bytes (1.0 kB) copied, 0.015222 s, 67.3 kB/s
-bash-3.2# dd if=/dev/zero of=/mnt/test bs=512 count=3
3+0 records in
3+0 records out
1536 bytes (1.5 kB) copied, 0.014824 s, 104 kB/s
-bash-3.2# dd if=/dev/zero of=/mnt/test bs=512 count=256
256+0 records in
256+0 records out
131072 bytes (131 kB) copied, 0.099793 s, 1.3 MB/s
-bash-3.2# dmesg -c
-bash-3.2#
So no problems here.
Rootfs NFS is mounted via e1000e of course.
Did you try with kernel.org 2.6.26 too? If not, please do so.
Best regards,
Stefan
