Root and usr are mounted over NFS from Netapp. Modules linux and linprocfs are loaded via loader.conf. System comes up ok, but execution of a linux binary, eg. "/compat/linux/sbin/ldconfig" causes panic. Instruction ptr is at "Xpage". I have union mounted /compat/linux under a read/write mounted fs (md in this case) so that /compat/linux/etc/ld.so.cache can be written, to rule out that problem. Since /compat/linux is writeable, so is /compat/linux/var also. >How-To-Repeat: Boot a diskless i386 system using pxeboot and root and usr on read-only nfs. Load linux kernel module. Try to run /compat/linux/ldconfig. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
