Aaargh, now I am getting it in pre8 as well. However I have made
I have 2 custom boards one mpc862(100Mhz, 16KB icache, 8KB dcache) and a
mpc860(80Mz,4KB icache, 4KB dcache). If I overclock the mpc860 to 100MHz I get
the same problem. If I set the clock on both boards to 95MHz all is well. If I overclock
the mpc862 to 105 MHz it works fine.
It turns out that syslog is actually running after the error. If I stop syslog and
start it again it works fine. If adjust my script so klogd is started before
syslogd all is well to.
This looks like a race somewhere to me, but i have no clue as to where.
