sporadic kernel panic during boot (MPC8xx, FEC)

Thu Apr 11 20:00:50 EST 2002

I have had this "random crashes" for linux 2.4.18-pre1 from
linuxppc-2_4_devel
for some time now, it was not to annoying, since so much other stuff has
been unstable for us. Theses crashses ware mostly during booting of the
kernel, i.e.
if the kernel made it through the boot it seemed to run stable. I
collected at one point some statistics and it crashed in 0.5% - 1% cases
of reboot.
I got 2.4.19-pre6 last weekend from the rsync source at mvista, merged
and compiled. Since
then I had the board in my "reboot loop" and rebooted some 6000 times.
Not one
single crash. So I am happy, and recomend to you to go get the latest
version from
linuxppc_2_4_devel (well I have version 2.4.19pre6 gotten from the rsync
source at
mvista last weekend).

Regards,

K.D.
