Does anyone else see these random coredumps?

My SS1+ has been annoyed by this problem since I updated the kernel
from 1.5_ALPHA to 1.5K (or 1.5L). 1.5-release kernel had no problem.
I tried to track this problem for long time, but got no clue..

There were some reports that IPX and SS1 had the same problem.
(sun4c only problem?)
