Thank you for the replies.
I realize that NetBSD doesn't do ext3... I figured if the journal was
properly re-played, that I could transfer the disk and use it as ext2.
No, I don't intend to move it back to Linux... Likely I will jungle some
things around, and move it to UFS. It's a 300G drive full of movies + my
/distros mirrors.

I'm moving it to NFS so that I can re-install the "media" machine
multiple times with different setups/etc.

I was able to get it mounted with nfsvers=2,udp options.
Yes, I also serve UFS file systems regularly to all sorts of clients
from a NetBSD 3.0 host.  Generally, I'm happier with NetBSD as NFS
server than Linux.

It certainly looks like it's the getdirent() code.
The thread you pointed to suggests that it's glibc's fault?
It seems to me like it's a fault in the ext2 handling of readdirplus() call.

- From an ubuntu host:

root@franklin:~# uname -a
Linux franklin.sandelman.ca 2.6.16-xen #3 SMP Mon Sep 11 19:59:33 EDT 2006 i686 GNU/Linux
root@franklin:~# mount aragorn:/kesey /mnt
root@franklin:~# ls /mnt/.
ls: reading directory /mnt/.: Input/output error
root@franklin:~# umount /mnt

TCPDUMP inline below.

One of the partitions on the moved disk is junk, so I newfs'ed it:

aragorn# uname -a
NetBSD aragorn.sandelman.ca. 4.99.6 NetBSD 4.99.6 (XEN3_DOMU) #2: Sat Dec 30 11:17:44 EST 2006  mcr@istari.sandelman.ca:/corp/network/kernels/compile-current/XEN3_DOMU i386
aragorn# newfs /dev/xbd2g 
...
root@franklin:~# mount aragorn:/psalm /mnt
root@franklin:~# ls -lt /mnt 
total 0

No problems with UFS.
(tell me if I should be updating my kernel)

I guess LFS is really what I should be using for such large partitions,
though.
