netbsd 4.0 hangs....deadlock detected.

["Hanns Hartman" <hwhartman%gmail.com@localhost>]

Hi,

So I have been searching the lists and have seen some bugs/emails
about seeing deadlock detected, but I didn't see any resolutions.  I
am running netbsd 4.0 on an Intel Xeon E3110 using the amd64 port.
The kernel is compiled to only use one of the cores on that processor.
 I am using the Intel S3210 system board.  I am experiencing a system
hang that is very reproducible, it sometimes results in deadlock
detected being printed and always results the system hanging.

Basically if you run:

dd if=/dev/urandom of=/home/user/data.out

The home directory is mounted on an LFS partition.

I have a serial console connected to the appliance so I can reproduce
the problem and try anything you would like.

The system will eventually lock up, usually less than 5 minutes.  I am
able to break into the kernel debugger and this is the output of bt:

# Stopped in pid 15.1 (pagedaemon) at     netbsd:cpu_Debugger+0x5:        leave
