freebsd stable - Mar 2005 - 5.4-PRERELEASE panics on boot with ipod shuffle plugged in

Hi folks,

when I have an iPod Shuffle(tm) inserted at boot in an USB slot,
the kernel panics before it reaches the point where it starts init.
This is on a Dell Dimension 4700 machine running FreeBSD 5.4-PRERELEASE
i386.  I get a fatal trap 12 panic.  Anybody else seeing this?  Is
it a known problem with the USB subsystem?  I can build a debug
kernel and try to produce a crash dump but that can take a while.

mkb.

Hi,

If possible, could you try updating to the latest 5.x-STABLE? I've
just finished merging all of the recent changes from -CURRENT, so
there is a good chance that things might work better now.

By the way, did you have `device ehci' compiled into your kernel?
The support for EHCI controllers is what should be most improved
by the recent updates.
