Bug#471062: ixp4xx: stalls and I/O errors when reading and writing via NFS
I recently upgraded my NSLU2 from etch/arm to lenny/armel. I had no
problems throwing any amount of NFS traffic at it when I was on arm
(kernel linux-image-2.6.18-6-ixp4xx version 2.6.18.dfsg.1-18etch1), but
now that I'm on armel I get a lot of messages from nfsd in dmesg.
nfsd: recvfrom returned errno 14
nfsd: non-standard errno: -14
The read problem manifests as mplayer stalling every minute or so when
playing a movie from the NFS mount. The write problem manifests as cp
or mv reporting an I/O error for one or more files when I copy 40 or
50MB worth to the NFS mount.
Bug #404447 sounded similar and with the tcp_wmem sysctl setting
suggested therein applied mplayer behaves itself. However, the
recvfrom messages are still logged and writes still throw an I/O
error now and then.
The network setup is the NSLU2 and the client connected by wired
Ethernet to a Linksys WRT54GL.
