Hang/reboot with -current and umidi on i386

[Tom Ivar Helbekkmo <tih%hamartun.priv.no@localhost>]

Hi all,

I'm trying to get a couple of USB MIDI interfaces to work on a very
current (Jan 24) -current i386, and running into problems.

The interfaces are Roland UM-ONE (not to be confused with the old UM-1),
and support for them is not present in /sys/dev/usb in -current.  I
added it myself, in a straightforward manner (patch appended below),
after having seen a couple of Linux discussion threads that concluded
with a configuration equivalent to that for the old UM-1 actually
working for this new interface.

Thus, I get:

NetBSD 5.99.60 (ATHENE) #7: Thu Jan 26 11:07:55 CET 2012
[...]
umidi0 at uhub4 port 1 configuration 1 interface 0
umidi0: Roland UM-ONE, rev 1.10/1.00, addr 2
umidi0: (Fixed Endpoint)
umidi0: out=1, in=1
midi1 at umidi0: <0 >0 on umidi0
umidi1 at uhub4 port 2 configuration 1 interface 0
umidi1: Roland UM-ONE, rev 1.10/1.00, addr 3
umidi1: (Fixed Endpoint)
umidi1: out=1, in=1
midi2 at umidi1: <0 >0 on umidi1

% midiplay -l
0: PC speaker
1: <0 >0 on umidi0
2: <0 >0 on umidi1

If I attach a synth to the second interface, and do

% midiplay -d 2 -x

the sample tune plays as it should.

The problem is reading from the MIDI device.  If I simply

% cat < /dev/rmidi2 > /dev/null

then the system immediately hangs (with the cursor still at the end of
the command line).  At this point, the box will respond to ICMP ECHO
from other systems, but will not give access to any services over the
net.  The mouse pointer does not move.  After a pause of somewhere
between 5 seconds and half a minute (this varies), the machine reboots.

Any hints as to where to start looking for the problem?
