See attached for my .config though note that it is almost exactly the
same as the one in your download area on the web site.

I do run ntp:

drt@cube:~$ dpkg -l | grep ntp
ii  ntp         4.2.0a+stable- Network Time Protocol: network utilities
ii  ntp-server  4.2.0a+stable- Network Time Protocol: common server
tools
ii  ntp-simple  4.2.0a+stable- Network Time Protocol: daemon for simple
sys
rc  ntpdate     4.1.0-8        The ntpdate client for setting system
time f

Reading the timer_interrupt() code you might find that the following
file which stores the rate of drift of the RTC might also help with
reproduction:

drt@cube:~$ more /etc/adjtime
-0.412188 1114242043 0.000000
1114242043
UTC

Agreed. After reading this I tried using another means to stress the BBA
and therefore the EXI bus. The following command issued from the 'cube
at my main Linux box caused a crash in less than a minute (with swap
to /dev/aram only):

drt@cube:~$ ssh starfish dd if=/dev/zero > /dev/null
