I had been trying to run nfsroot with kernel 2.6.7 on the machine, and could not get it to work: IP-Config: Guessing netmask 255.255.255.0 IP-Config: Complete: device=eth0, addr2.168.1.7, mask%5.255.255.0, gw%5.255.255.255, host2.168.1.7, domain=, nis-domain=(none), bootserver2.168.1.1, rootserver2.168.1.1, rootpathLooking up port of RPC 100003/2 on 192.168.1.1 eth0: Link is up using internal transceiver at 100Mb/s, Full Duplex. portmap: server 192.168.1.1 not responding, timed out Root-NFS: Unable to get nfsd port number from server, using default Looking up port of RPC 100005/1 on 192.168.1.1 portmap: server 192.168.1.1 not responding, timed out Root-NFS: Unable to get mountd port number from server, using default mount: server 192.168.1.1 not responding, timed out Root-NFS: Server returned error -5 while mounting /usr/local/sparc VFS: Unable to mount root fs via NFS, trying floppy. VFS: Cannot open root device "" or unknown-block(2,0) Please append a correct "root=" boot option Kernel panic: VFS: Unable to mount root fs on unknown-block(2,0) <0>Press Stop-A to return to the boot prom On a suggestion from Ciaran McCreesh, I recompiled my kernel without SMP support, and was able to mount nfsroot with no problems at all. I also successfully compiled and booted a 2.4.27 smp kernel with nfsroot, and had no such problems. Steve Becker
