Yeah, I was given a zip of the driver a little while before he posted the
patches to the list.

I don't recall xfs taking /that/ long for a 4TB fs. With 2.6.34 I don't see
any HDIO_GET_IDENTITY messages in dmesg. But I'll bet it freaks out if I try
and hot remove one of the drives. I remember seeing the card lockup, and/or
the kernel oopsing the last time I tried (2.6.30-2.6.32 time frame).
Thankfully its not something I often do. While I Can, since I have a hot
swap unit, its just not something I've had to do yet.

This array has been pretty solid for the past 6 months. Not sure it helps
but I've been very careful with this machine, it gets shut down
automatically and safely when the UPS battery gets low, so there hasn't been
any abrupt shutdowns, except today when a forkbomb hit, and I had to
SYSRQ+S+U+B the box.

At any rate I can help test whatever new patches might come along.
