OMAP2420 cache corruption still exists with source from 
Thu Jan 8 23:31:33 2009 +0000 (last commit to tree, includes Matt's 
latest pmap change). ARM9 OSK5912 is ok.

The boards run with a swap file on NFS to avoid OOM situations with -j 3
builds.

6 kernel builds from 27 over the weekend failed with these errors:

../../../../nfs/nfs_vnops.c: In function 'nfs_create':
../../../../nfs/nfs_vnops.c:1639: internal compiler error: Segmentation
fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.NetBSD.org/Misc/send-pr.html> for instructions.
