Personally, I have the following machines running the following kernels:
- 2 main development boxes (work and home) running 2.5.latest
- 1 laptop running 2.5 latest
- 2 test servers running 2.5 latest
- 1 server with things I care about on it running 2.2.20
So for me, I've had no problems with the 2.5 kernel, even with a wide
range of different hardware (SCSI, IDE, wireless, different processors, etc.)

Wait, you forgot:
o USB host controller interface changes
o USB urb handling logic change
aren't you afraid of them too? :)

Fine, doesn't bother me. But for now, all new USB development needs to
show up in the 2.4 tree. After it's proven for a bit can it be
backported (like the USB 2.0 support was, and the urb handling logic
will be.) Bugfixes are gladly accepted into both trees, as long as they
do not involve major changes (like the usb-serial locking and reference
counting fixes did, that is why those changes showed up first in 2.5.)
thanks,
