[Bug 561210] Re: Writing big files to NFS target causes system lock up

[JimWright]

Tim:

I managed to get your dd testcase to trigger the issue on a VM running
Ubuntu 10.04, Kernel 2.6.32-24.42, 8 CPUs, 512MB RAM, 8GB HDD.  I've
attached the dmesg output from that test.

I downloaded the latest daily snapshot of Maverick Ubuntu 10.10 (kernel
2.6.35-19.28) and installed it onto an identically configured VM.  I was
unable to trigger the issue I have seen using either my gzip testcase or
your dd testcase after many hours of runtime.

So it would seem that the issue has been fixed in a more recent kernel,
and that needs to be backported to the Ubuntu 10.04 kernel?
