Could you give r186860 a try? It is an MFC into stable/7 so if the
machine in question is something you can experiment with just updating
to stable/7 would take care of it. Otherwise if you could just manually
apply the patch to a 7.1 source tree and do a test build of the kernel
that would also do it.
I'm not experiencing lockups but this patch helped a lot on a machine I
have with a particular disk I/O pattern that resulted in extremely poor
performance with 7.1-RELEASE. This patch brought it back to its normal
performance level.
Thanks.
