That's a great interface!  I like the log on mouseover bit.  An RSS
feed is something that I've found extremely useful; I can check the
results when I get in of a morning along with all my other RSS feeds.

Ok, so you're grabbing the patches from kernel.org?  We have found it
useful to do the pull directly via git (well, used to be BitKeeper)
every night to keep right up to date.

We also find it useful to build all the defconfigs for IA64; some
other architectures also have multiple defconfigs for different
classes of machine.  Luckily, for IA64 the defconfig builds probably

Yes, that would be very nice; I think OSDL provide something similar
to that (http://www.osdl.org/lab_activities/kernel_testing/stp/) but
I've found their interfaces to be a little difficult at times.

Ours is nothing fantastic, just hacked together shell and PHP code,
but it works.
