We have 4Mb of ram and 2Mb of Flashrom. We load the kernel from the Flashrom and attemp to mount the root file system over NFS. I am wondering if this could be related to memorysize, i.e we are seeing some kind of memory starvation? I will try to find a bigger simm and try with bigger memory. Below is the output of the boot process. loaded at: FE100000 FE111BAC relocated to: 00100000 00111BAC board data at: 001001C4 001001E0 relocated to: 00200100 0020011C zimage at: FE120000 FE16B357 avail ram: 00201000 00400000 Linux/PPC load: root=/dev/nfs nfsaddrs=192.168.145.220:192.168.145.222 nfsroot=1 92.168.145.222:/usr/local/embedded Uncompressing Linux...done.
