I haven't had alot of spare time to make much progress on this. I'm now at a point where the openrd and sheevaplug are failing at the same point of the boot process; when trying to extract the root path from the DHCP request similar to this: http://lists.freebsd.org/pipermail/freebsd-arm/2013-March/005325.html The openrd also drops into the debugger every few boots as mentioned in my previous mail: Sending DHCP Request packet from interface mge0 (f0:ad:4e:00:61:58) Received DHCP Ack packet on mge0 from 192.168.0.10 (accepted) (got root path) mge0 at 192.168.0.16 server 192.168.0.10 boot file openrd/kernel.bin subnet mask 255.255.255.0 router 192.168.0.1 rootfs 192.168.0.10:/mnt/work/nfsroot/arm-8-le hostname openrd Adjusted interface mge0 krpc_call: sosend: 64 krpc_call: sosend: 64 panic: nfs_boot: mountd root, error=64 KDB: enter: panic [ thread pid 0 tid 100000 ] Stopped at kdb_enter+0x48: ldrb r15, [r15, r15, ror r15]! db> I'm still using the same version of current, and haven't seen a repeat of the RPC timeouts with the sheevaplug mentioned in my first mail. I tried building a copy of i386 current to test diskless booting, but ran into problems with buildkernel: aicasm_gram.c:1539: warning: no previous prototype for 'yyparse' *** [aicasm_gram.o] Error code 1 Stop in /mnt/work/obj/mnt/work/src/sys/GENERIC. The best approach is probably to test arm kernels built with a fixed ROOTDEVNAME. I hope to find the time to have a go at this on Monday. Jeff
