If its the same bug we've seen it appeared in 2.6.17 and we "fixed" by
downgrading the involved hosts to 2.6.16. It was related to this post
by Trond Myklebust (in Jan/Feb) :-

That is very likely to be the same problem as fixed in

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=5d47a35600270e7115061cb1320ee60ae9bcb6b8

AFAICR, all kernels after 2.6.17 were affected. Can you therefore see if
the same patch applies to 2.6.19, and if it fixes your problem?

Cheers
Trond

Sincerely,
