Heip!
I managed to get an OOPS on latest -mm kernel while playing with PDA using
USB connection:

I was using KPilot 4.3.10 (KDE 3.1.3) at the time. The second OOPS seem to
be result of the first.
I had following patch included to get kernel recognize Handspring Orange
PDA/phone, but I don't think it affected things. (The PDA OS was PalmOS 5.2.1.)

My .config is attached, and my distro is Gentoo (I used gcc 3.3.1 to compile
the kernel).
