We're seeing exactly the same thing on one of our R610s. We've got two in
production and every time we upgrade the kernel on one of them, we're
seeing it hang.

I've not been dealing with the problem at our end so I don't know what
steps my colleagues have taken. They've tried replaying the problem but it
always behaves perfectly when they watch.

We're running with four 73Gb SATA disks in RAID 10 with 24GB RAM and two
2.4Ghz processors.

Will try and get some more diagnostics next time the system fails.
