Hi,
I've got an unusual problem with a corner case that I
am investigating. I've tried 'googling' around to
find if someone has discussed this before, but
I have yet to find any discussion close to this -
so I bring it to your collective minds...
I am working with a 2.6.11++ kernel on an embedded
server platform that is NFS serving Linux rootfs
for other embedded NFS Client boards.
Everything works fine when the system time on the
server board is relatively synchronized with the real-time.
It hangs after attempting to update the time from a
nonsensical time (e.g.: 2 months ago) - the most significant
part of it is that it only hangs IFF it has started
serving its NFS client boards before I attempt to
update the time.
The most significant output (when turning on
RPC debugging) is from:
linux/net/sunrpc/cache.c (cache_check) - line 90:
>> Want update, refage=1800, age=4288285
It continually loops through this method - and the cache
never gets updated...even thought with some additional
sleuthing (aka: additional debug printks - it thinks
that there is an cache update pending).
Thanks for any ideas you have on this subject.
Sincerely,
Tom Morrison
